The Differences between Windows 8 and Windows RT Explained

 

 

As Windows 8 and its accompanying devices has launched on Oct. 26, you probably need to make sure you know the differences between the various flavors of Windows 8 before purchasing a device or upgrade pack. Microsoft has released three consumer versions of its new operating system: Windows 8, Windows 8 Pro, and Windows RT.

While there are some small variations between Windows 8 and Windows 8 Pro, the biggest differences lie between those two — which have a full-featured Start Screen and desktop environments — and Windows RT, which is a mobile environment that runs only Windows Store apps and built-in software.

These aren’t cosmetic differences; Windows 8 and Windows RT look nearly identical, with the new tile-based Start Screen UI and the available desktop mode. But the under-the-hood differences have a significant impact on how you can use your devices — Windows RT is a tablet- and mobile-focused OS, while Windows 8 is a full-featured PC operating system. They look the same but behave entirely differently, which, obviously, leaves room for confusion.

Microsoft says that it’s working to ensure its store employees know the differences between Windows RT and Windows 8, but as The Verge found, that’s going to take some time. Even with Surface RT pre-orders open, many Microsoft employees were unable to explain what Windows RT could and could not do.

In the interest of helping them — and you — here’s a breakdown.

 

Windows 8


Windows RT


Hardware

Windows 8 will only run on devices, powered by Intel or AMD chips.

Windows RT will only run on ARM-powered devices. ARM chips tout better battery life and lower prices.

Battery Life

Upcoming Windows 8 devices tend to have an estimated battery life between 6 and 8 hours.

Windows RT devices promise longer battery life than most Windows 8 devices. Microsoft says that Surface RT will have “all-day” battery life, or between 8 and 13 hours. Dell claims that its upcoming XPS 10 RT tablet can get up to 20 hours of battery life.

Interface

Full-featured Start Screen and desktop mode.

At first look, Windows RT has the same interface as Windows 8. But while Windows RT has a desktop mode, it is far from full-featured. In fact, you won’t be able to run any third-party software on the desktop in Windows RT, not even different web browsers like Firefox or Chrome. (See more below.)

Software Support

Windows 8 will be able to run all software from the Windows Store and any third-party programs that you may have used in earlier versions of Windows.

Windows RT only supports apps from the Windows Store and its built-in version of Office 2013. This means you won’t be able to download any software from the web that is made to run in the desktop environment. No third-party browsers, no third-party games, no third-party anything. Everything you run on Windows RT has to be approved by Microsoft and available in the Windows Store.

Currently the Windows Store has around 5,000 apps, more than 90 percent of which are compatible with Windows RT. It’s not a terrible number of apps, but there are some key missing players like Spotify and Facebook. Windows RT also does not port Windows Media Player, though it does come with other build-in media players like Xbox Music.

Business Use

While Windows 8 is a drastic shift from previous versions of Windows, it does support the tools business users need. Windows 8 Pro offers a Remote Desktop server, Active Directory domain support, Encrypting File System, Hyper-V, BitLocker and more.

Windows RT is not necessarily a business-friendly platform. Because it is so closed off to third-party software, users will have to depend on the built-in Microsoft apps to do work. The built-in RT version of Office 2013 does not come with common business software like Outlook. But at least you will get Word, Powerpoint and Excel. A Windows RT device like Surface RT could potentially be a good additional business tool, but if you want a full-featured enterprise platform, you’ll need to go with Windows 8.

Who Should Buy

You should buy Windows 8 if you want to have a full-featured operating operating system with an actually useful desktop mode. If you depend on third-party software, then stick to Windows 8 and Windows 8 Pro. The system is built for notebooks, desktop PCs, and convertible devices.

If you want a tablet or mobile converible that functions like the iPad, then a Windows RT device is a good fit. The Surface RT, for example, is enough for somebody who wants basic productivity tools like Office alongside the touch- and mobile-friendly environment. Just remember that Windows RT is limited to apps in the Windows Store, which is not very robust yet.

Difference between LCD, LED, OLED, PLASMA, CRT, 3D TV.

 

Always there is a question in our mind that how we can see the picture in a TV . The answer is based on very simple principle that is the light plays the vital role behind the TV screen.

The light adjusts itself to create different color of images, which we can see on the TV screen. So basically the back-light play technology is different for LCD, LED, OLED, PLASMA type devices. Let’s have a comparison between all types of displays like TV that are available in market now. Let’s start from the latest display technology known as OLED.


• OLED (Organic Light Emitting Diode) is simple a light emitting diode(LED), in which a thin film layer of organic compound is present for creating images.


Features


1. It has the highest image clarity. Specially for motion pictures like movies. Because each OLED unit has its own light emitting capability unlike LED/LCD, each unit can adjust itself without depending on other units.


2. It has larger viewing angle and for near-eye applications, it provides more pleasant viewing without distortion of images.

3. It consumes less electricity as compares to other display devices. Because it does not required any cooling or heating and back-lights as well.


4. OLED pixel colors appear correct and unsifted, even as the viewing angle approaches 90° from normal.

Limitations



1. The biggest technical problem is the life time of organic material which is used in this technology. The average life time of OLED is 25,000–40,000 hours, depending on manufacturers and models.


2. Water can damage the organic materials of the displays. So it needs proper care.

• LED (Light-Emitting diode) is a semiconductor light sours used as indicator lamp in many devices. It is simple a LCD that uses LEDs for back lighting, which creates images/Pictures in display devices like TV.

Features


1. Brighter picture can be viewed as compared to LCD & CRT devices.


2. Edge-lit LED TV consumes 30-40% of less power than LCD or plasma TV, but backlit LED consumes more power. The average life time of LED is 25,000 to 100,000 hours.

3. It has a long lasting life and also eco-friendly in nature.

Limitations


1. The cost is very high as compare to LCD & CRT.


2. Temperature dependent. That means, an adequate heat sink is needed to maintain long life.

• LCD (liquid crystal display) is a display that uses the light modulating properties of liquid crystals. Liquid crystal does not emit light directly. It required separate light source for creating images. For a LCD the lamps at the back of the screen are fluorescent lamps, which provide light for creating images.

Features


1. They are ideally used for mobile phones display, computer monitors and for view still images.


2. LCD televisions are thinner, lighter, sharper and providing clearer picture than CRTs.


3. Low power consumption. It consumes 50-70% less energy as compared to CRT monitors.


4. Not affected by screen burn-in like CRT and Plasma TVs.


5. The average life time of LCD is 60,000 hours.

Limitations


1. Poor display while watching in direct sunlight.


2. It has limited viewing angle and causing color, saturation, contrast and brightness to vary, even within the intended viewing angle.

• PLASMA


Plasma Display Panel (PDP) is a flat panel display. They are called “plasma” displays because it contains small cells containing electrically charged ionized gases.

Features


1. The phosphorus lights up themselves to create the image on the screen and does not require back light.


2. plasma screens can still display ‘blacks’ more accurately than LCD can, that means better contrast and detail in dark scenes.


3. Better viewing angle than LCD.

Limitations


1. Power consumption is higher than LCD.


2. Heavy in Weight as compare to LCD.


3. Does not work well at high altitudes above 2/3 km due to pressure differential between the gases inside the display screen and the air pressure at altitude. It may cause a buzzing noise.

• CRT (cathode ray tube). As we know CRT is the first technology for display devices like TV. For many years, the CRT technology was the dominant technology in television industries. CRT is a vacuum tube which contains an electron gun and a fluorescent screen (called picture tube) used to view images. When the electron gun fires towards the picture tube, it creates image/picture.


Features


1. As CRT technology was the first step for Display devices & at that time, no LCD, LED PLASMA, OLED exist, so it is not a good idea to compare the features with other display types.

Limitations


1. Power consumption is high.


2. Large size and weight.


3. Produces noticeable flicker at low refresh rates.


4. It produces a heat when running.

• 3D TV 3D television (3DTV) conveys depth perception to the viewer, which employing techniques such as stereoscopic display, multi-view display and etc.


There are two different type of technology for 3D TV, one is converting the 2D images to 3D images and the other one is, it is recorded by 3D technology camera & display it the supported 3D TV.


While watching 3D video or movies, you required a special type of glasses. Now a day’s most of the TV programs are not 3D recorded, so if you buy a 3D TV set, then you cannot take the full advantage of it, however you can use it in future when 3D technology will be more popular.

 

Quad-Core Tablets Offer Increased Speed and Battery Life

 

The next wave of tablets promises faster video and app performance.

Tablet computers grow more popular by the day. New quad-core models promise to accelerate that trend, offering enhanced video processing and longer battery life, features that will make the devices more enticing to faculty, students and staff.

NVIDIA is at the heart of this development in the tablet market. The California manufacturer's Tegra 3 quad-core processor offers improved performance and uses 61 percent less power than a dual-core tablet doing the same tasks.


The Tegra 3 mobile chip actually includes five ARM Cortex-A9 CPU cores: four 1.6-gigahertz main cores and one 500-megahertz companion core. The companion or battery-saving core handles low-power tasks, such as Facebook updates or music streaming. Once the workload exceeds a certain power threshold, the Tegra 3 switches to the high-performance cores and disables the companion core, says Nick Stam, NVIDIA's director of technical marketing. "The processor is very intelligent, and it dynamically monitors the workload," he says.

A faster tablet that runs up to 12 hours between charges and supports high-quality 1080p video. The Tegra 3 powers quad-cores from Asus, Acer, Toshiba and Lenovo.

Great Minds Think Alike

Other manufacturers are thinking along similar lines. Samsung, which offers the Galaxy Tab dual-core tablet, points to the speed and efficiency of multicore processors.

"Implementing multicore processors into the Galaxy Tab product line empowers us not only to achieve rapid computing speeds, but also to maximize battery life," says Travis Merrill, Samsung America's director of marketing for the Galaxy Tab.

Still, industry analysts caution that significant performance gains must await applications designed to take advantage of quad-core chips, though users may see an immediate improvement in games or other complex computing applications.

The researchers see quad-core processors as a first step toward real performance improvements across the board. Quad-core tablets promise to let users multi-task more easily, which will offer an enhanced experience, they predict.

 

Wi-Fi and mobile Internet (2G, 3G, 3G+ and 4G)

 

 

What's the difference between Wi-Fi and mobile Internet (2G, 3G, 3G+ or 4G)? Surfing via Wi-Fi is cheaper than surfing via mobile Internet, but Wi-Fi coverage is limited to a building or a district.


 


· Wi-Fi uses a local wireless network to transfer information. 
Its coverage is therefore limited to a building (pub, airport, etc.) or a district. Access can be private or public, paying or free of charge, open for Internet or not.

o To surf on your phone, you must have a Wi-Fi device.

o To surf on your computer, you must have a Wi-Fi modem or a computer with a built-in Wi-Fi modem.

· Mobile Internet (2G, 3G, 3G+ or 4G) uses a mobile telephony network to send and receive data. 
With your SIM card, you access the Internet everywhere.



o To surf on your phone, you must have a 2G, 3G or 4G device.

o To surf on your computer, you must have an external USB modem or a computer with a built-in mobile modem.

Your device will automatically connect to the best mobile network available. It may happen that you switch from one network to the other.


You can use the following mobile Internet networks: 2G (GPRS or EDGE), 3G (UMTS), 3G+ (HSDPA or HSPA+) and 4G (LTE).

o With 2G

§ With GPRS (General Packet Radio Service), you have a theoretical transfer speed of max. 57.6 Kbps.

§ With EDGE Type 1MS (Enhanced Data Rates for GSM Evolution), you have a theoretical transfer speed of max. 250 Kbps.

o With 3G or UMTS (Universal Mobile Telecommunications System), you have a theoretical transfer speed of max. 384 Kbps.

o With 3G+

§ With HSDPA (High-Speed Downlink Packet Access), you have a theoretical transfer speed of max. 14.4 Mbps.

§ With HSPA+ (High-Speed Packet Access +), you have a theoretical transfer speed of max. 42 Mbps.

o With 4G or LTE (Long Term Evolution), you have a theoretical transfer speed of max. 173 Mbps.

 

How HDMI works

 

 

If you've shopped for an HDTV, a PlayStation 3, or an HD-DVD or Blu-ray pla­yer, you've probably heard about HDMI. It can seem like just one of many connections on televisions or home-theater receivers. But HDMI is more than a port on the back of a TV (and the often expensive cable that fits inside). It's a set of rules for allowing high-definition electronic devices to communicate.

Before the development of high-definition televisions, most TVs displayed pictures in what is now known as standard definition. The picture was roughly square -- its aspect ratio was 4:3. Its resolution, or the number of dots that make up the picture on the screen, was about 704 x 480 pixels. The picture was interlaced -- each piece of the moving image was really half a picture, but the pictures changed quickly enough that the human brain didn't really notice.

HDTVs, on the other hand, are digital. They use information in the form of ones and zeros. This information travels through cables as distinct electrical pulses. HDTVs have an aspect ratio of 16:9, so the picture is rectangular. They also have a higher resolution -- current HDTV standards allow for resolutions of up to 1920 x 1080 pixels. HDTV signals can also be progressive, meaning that the each frame of the moving image is a whole picture rather than half of one.


­So, compared to standard TVs, HDTVs have a wider screen, more pixels and a faster refresh rate. Often, HDTVs can display more colors than older sets. This means that HDTVs need more data and need it a lot faster than standard-definition TVs do. If an HDTV can receive this information digitally, it also doesn't have to spend time or processing power converting the signal from an analog format.

This leads us to HDMI. Created by a group of electronics manufacturers, the HDMI standard is a set of guidelines for creating high-bandwidth connections between digital devices. With the right setup, HDMI can make a significant difference in a home-theater system. The current standard can carry 1080p high-definition signals, and it supports eight channels of uncompressed audio, enough for a 7.1 surround-sound system. HDMI can cut down on the number of cables required to connect components, and it can even reduce the number of remote controls needed to watch a movie.

 

Touch Screen

 

Touch screens and touch monitors are available for a wide variety of uses, from point of sale to kiosks, medical and industrial equipment, and gaming systems. Advantages of solutions include their reliability, accuracy, clarity, responsiveness, and ease of installation and use. As we all know different Industries require different touch screens. We can help you to choose the right touch screen for your application.

Types of touch Screens

When it comes to touch screen technology, the four most prevalent types are Capacitive, Infrared, Resistive, SAW (surface acoustic wave). Resistive and Capacitive being the most widely used types for Industrial Applications. All of these technologies have their own distinct characteristics, both advantageous and with limitations.

Capacitive Touch screens

Capacitive touch screen technology is recommended for use in KIOSK applications that require a "finger touch". It will not operate with either a gloved hand or with a mechanical stylus. It is made of glass, which makes it extremely durable and scratch resistant. This glass overlay has a coating that stores the charge deposited over its surface electrically. Capacitive touch screens operate using oscillator circuits that are located in each corner of the glass overlay and measure the capacitance of the area be "touched". Depending on where the person touches the overlay, the oscillators will vary in frequency. Then a touch screen controller measures the frequency variations to ascertain the coordinates of the person's touch. When used with flat panel displays, capacitive offers drift-free stable performance that is not susceptible to deterioration over time. A capacitive touch screen is impervious to grease, dirt and water, which makes it ideal for frequent use.


Resistive Touch screens

Resistive touch screen technology is recommended for use in POS (Point of Sale): Grocery Stores, Hotels, Restaurants and Retail Stores; Industrial Applications: MMI (Man Machine Interface), Machine and Process Control; Portable Devices; Personal Information Management Systems; Transportation Solutions; Medical Solutions: Equipment, Instrumentation and Patient Monitoring Systems. It generally uses a display overlay composed of layers, each with a conductive coating on the interior surface. Special separator "dots" are distributed evenly across the active area and separate the conductive interior layers. The pressure from using either a mechanical stylus or finger produces an internal electrical contact at the "action point" which supplies the controller with vertical and horizontal analog voltages for data input. Resistive technology offers tremendous versatility in that activation can be initiated by; a gloved hand, fingernail, mechanical stylus or an ungloved finger. Limitations include: Low light output, diffused resolution images and a plastic surface which can be scratched if improperly touched.


SAW (Surface Acoustic Wave)

SAW touch screen technology is suggested for use in ATMs, Amusement Parks, Banking and Financial Applications, Gaming Environments, Industrial Control Rooms, and KIOSK. It has excellent durability that allows it to continue working if scratched since the overlay for the touch sensor is a solid glass display. The disadvantage to this glass overlay is that is breakable and won't work in wash down conditions. The waves are spread across the screen by bouncing off reflector arrays along the edges of the overlay. The waves are detected by two "receivers". The acoustic wave weakens when the user touches the glass with their finger, gloved hand or soft stylus. The coordinates are then determined by the controller circuitry that measures the time at which the amplitude declines. It is the only technology that can produce a Z-coordinate axis response. SAW technology offers drift-free stable performance that is always precise. SAW offers superior image clarity, resolution, and high light transmission.


Infrared Touch screens

Infrared touch screen technology is becoming increasingly replaced by Resistive or Capacitive touch systems. Over the years, Infra-red bezels have proven to be a very reliable technology for use in ATMs, Food Service and Preparation, KIOSK, Medical Instrumentation, Process Control Systems, and Transportation Tracking applications. It does not incorporate any sort of “overlay” that could inhibit screen clarity or brightness, but instead, uses a special bezel of LEDs (light emitting diodes) along with diametrically opposing phototransistor detectors which surround the glass of the of the display surface. The controller circuitry scans the screen with an invisible lattice of infra-red light beams just in front of the surface that directs a sequence of pulses to the LED’s. It then detects information at the location where the LEDs have become interrupted by a stylus or finger.


 

eBook Reader?

 

Have you been hesitant about making the switch from holding a physical book to holding an eBook reader and reading an electronic book? We understand. Many of us have had the same reservations; however, with the low price of eBooks and the affordable price of eBook readers, along with their convenient storage, portability and versatility, more and more users are making the switch to eBook readers every day.

So why should you buy an eBook reader? Convenience. Instead of going to a bookstore to make a purchase or ordering a book online and waiting for it to arrive, you can purchase and download an eBook anytime, from any location with a Wi-Fi connection. Several classic books are free to download because their copyrights have expired, and when you don’t have to pay for printing, you don’t have to pay.

Want more than one book? That’s fine. The memory of eBook readers is large enough to hold several hundred books. eBook readers are the only way to carry countless books with you wherever you go, and keep the weight under a pound.

You want more convenience? eBook readers make it easy to save your place, take notes, clip and save favorite quotations, and highlight passages you want to find again. eBook readers are designed for readability and to make your reading experience as enjoyable as possible.


What to Look For

With the variety of eBook readers available, you really get the opportunity to pick and choose the features and design that fit you best. Here are the factors that we took into consideration when ranking and comparing eBook readers.

Design
Some eBook readers offer E-Ink technology that makes you feel more like you are reading an actual book, while others offer LCD color screens that make images and movies come to life. Some offer button navigation and some have touchscreen navigation. Which is better for you? Does screen size matter? Do you want to know how much they each weigh? While some design aspects will depend on the user (E-Ink vs. LCD), we were able to find the eReaders with the best resolution, the easiest navigation and the most impressive build.

Content
Some eReaders have hundreds of thousands of titles available from a dedicated service, while others can support a few files found on the internet. We rated the amount of content available for the device and how many different files each device can support. Obviously, the more file types the better, because that gives you more reading options.

Memory/Battery Life
The battery life of your eReader is crucial. Nobody wants their reading devices to run out of power before the climax of their novels. The numbers of pages that you can turn on a single charge and the amount of memory available for storing books are important for making the eReader experience more enjoyable.

Additional Features
There is always room for extra features to enjoy while reading a book. Some of these include the number of gray scale levels, audio formats, image formats, text-to-speech feature, apps, email, internet surfing and so much more.

We found that the best eBook readers have a good combination of abilities in all of the above categories. They offer convenience and the opportunity for the eBook reader to disappear in your hands, just like a physical book would, as you dive into the world of reading.

 

A Comparison of SSDs and HDDs

 

Dependability

• SSD: By and large very dependable and retains data after accidental collisions or drops. The SSD does not have any moving parts and therefore does not have the issues with mechanical wear or malfunctions.

• HDD: Dependable in retaining data but can be compromised in case of accidental collision or drops. The hard drive is made of magnetic disks and is primarily mechanical and do wear out after time and can malfunction from mechanical complications.

Data Speed

• SSD: Extremely efficient in data storage and retrieval. Without the mechanical process, the SSD can quickly store and retrieve data the stays in place and never becomes fragmented.

• HDD: The hard drive is mechanical and needs more time to locate and retrieve data; they can store data but not in a manner that is consistent, and becomes very fragmented after some time which can further slow the retrieval process.

Technology

• SSD: Made from the latest technology and manufactured much like RAM, but it is not a volatile memory. It is made of a series of chips that are interconnected and used to store the data.

• HDD: A much older technology and made of one or several magnetic disks that are used to store data. Usually there are two to three disks that depend on a mechanical arm to move back and forth to retrieve or store data.

Size

• SSD: Not a technology that to date has the ability for large data storage capacity in conventional sizes.

• HDD: Has the ability to store vast amounts of data and is very useful for databases and large data storage needs.

Capabilities

• SSD: Has many unusual capabilities and features that protect data integrity. The durability and portability makes it a much better choice for notebooks and tablets.

• HDD: Has the ability to store vast amount of data and although it needs more maintenance and upkeep, it's a better choice for large storage and database needs.

Price

• SSD: Solid state drive technology causes these drives to be far more expensive and not very cost effective in many aspects of use.

• HDD: Very cost effective and can be implemented in all manner of scenarios for a fraction of the cost per gigabyte of storage space.

As you can see there are many pros and cons with both of these technologies. They both have very practical uses that can be beneficial to different types of implementations and uses. The deciding factors will have to be made on the expectations of the product and on which application is better for the desired outcome, as well as cost factors. Both are useful in their own ways, so the decision is up to you.

What's the Difference Between MP3, MP4 and MP5?

 

When you're looking for a device that lets you play music and perhaps also watch videos while you're on the go, the hardest thing is probably figuring out which one to buy. There are so many different digital media player models out there that it's easy to get confused. Then there's also the question of whether you want an MP3, MP4 or MP5 player. And what's the difference between them anyway?

MP3 players have been around for several years now, so you have probably used one at some time, or played MP3 music files on your computer or cellphone. MP3 is a file format for audio files, which can also be played on media devices made for later file formats. Portable MP3 players are still very popular

Like all media players, portable MP3 devices are available with various storage capacities. The smallest versions come with a memory chip, while there are models that let you store your entire music collection of, say, 30 gigabytes, on an internal hard drive. However, even a tiny 1GB player has room for 500 tracks, and some of your favorite photos as well.

MP4 is also a file format, properly named MPEG-4 Part 14, and is used for storing and playing videos. An MP4 player is thus a significant upgrade from the previous version as it can play not only audio files but also movies and video clips. In addition, most models will also play files in other formats such as AVI, WMA and WAV.

The LCD screen is usually larger than on an MP3 player, for the obvious reason that you need to be able to view videos comfortably. A lot of MP4 multimedia players sold these days also let you play games, listen to FM radio and read eBooks, as well as taking photos and shooting video with an onboard DV camera.

Now that you can also buy MP5 players you're probably wondering what the extra features are and whether it's worth getting one. One thing you should know is that there is no MP5 file format it’s simply a trade name that is used by Chinese manufacturers to show that these are more advanced than MP4 players. You'll also see some products sold as MP4/5 players but most of these are just MP4 devices with some extra bells and whistles.

The general definition of an MP5 media player is one that supports a wide range of video and audio file types. This means the user doesn't need to convert the file to an easily playable format, the way he would with a previous-generation player if he want to play something recorded in RM, RMVB, Divx, 3GP, ASF, DAF, FLAC or APE, for instance. Many MP5s do a lot of other extras such as enhanced sound quality, so you'll probably be pleasantly surprised at how much you get for your money.

Whichever type of portable media player you go for, make sure you’ve considered your needs first. If you just want to be able to listen to music while you go jogging or work in the yard, a tiny MP3 player that clips onto your belt or hangs around your neck could be ideal. However, if you also like the idea of watching movies, reading or playing games while you’re on the train or just relaxing at home, you’ll need an MP4 or MP5 player. Remember that they all come with earphones, and that most can also be connected to external speakers, so they can truly be used in a variety of situations.

 

Smartphone, Tablet, Laptop, Netbook: What should you buy and Why?

 

 

 

Smartphone , Tablet ,Laptop ,Netbook : what should you buy and why?

The world of personal computing is changing. What needed almost a building to operate 4-5 decades ago, now fits into your purse without any fuss thanks to the increasing computing power and a corresponding decrease in size. Earlier there was Desktop/Personal Computer (PC). Laptops were invented to give a person ability to take his computer along with him anywhere. Smartphones were invented to give a person usual mobile phone services, along with computer like functionality.  Tablet PCs were invented to give a person more computer features in a smartphone.

Growth of mobile device

But a question always lingers: Between a smartphone, netbook, laptop and tablet, which should you buy? With laptops falling in price, netbooks features rising and smartphones commanding more, the price range of tablets progressing. So what should one consider before making a purchasing decision? It depends on why you need it, what will you use it for. This post might help you in understanding these gadgets, highlighting the features and differences.

Smartphones

A smartphone is the simplest of the four mobile computing device types. They offer the usual mobile phone service, talking and messaging, enhanced with other, computer-like functionality. Smartphones can access the internet using wireless signals from mobile phone carriers (GPRS), although they can also use the wireless signals (Wi-Fi) too. They use a mobile web browser to access the internet. They run programs called apps. Apps are designed by third parties, which means you can find a one for just about anything at this point.  You do little ‘snippets’ of things like checking an email, play games like Angry Birds etc.


Tablets

Tablets are very similar to smartphones but on a bigger scale. Tablets have the large screen (7-10 inches) but are portable enough to carry around. A tablet computer can slide easily into most bags and weigh only a few pounds. They contain a mobile Operating System (OS) and user interface so the experience is more like a smartphone.  Tablets are great for reviewing and responding. You can turn it sideways to more easily review web pages and watch movies and TV shows.


Laptops

Laptops support the same power and functionality as full desktop computers but do so in a mobile form. They have large screen, keyboard, web browser, software programs like Microsoft Office (Word, PowerPoint, Excel, Outlook and etc.), can play CDs and DVDs. They can access the internet. The higher-power CPUs coupled with more memory (RAM) allow for smoother multitasking.


Netbooks

Netbooks were designed as ultra-portable versions of laptops, focusing on accessing the internet and doing basic computer functions. They work very much like laptop computers but save a lot of weight and size by not using CD or DVD drives, having smaller screens and keyboards. But they don’t actually do anything better or faster than laptops, cannot help you run complex office software or project content on your TV. Also, you cannot watch high-definition (HD) movies or encode music. Working on video files, and their editing and mixing can be a problem on slow-running netbooks.

The importance of tablets and smartphones protection

 

Many people believe that smartphones and tablets are not susceptible to viruses, spyware and other malware. This is certainly not the case ... in fact the more people that use these devices, and the more apps that are available for them, the greater the level of harmful and criminal activity.  

The Risks

Viruses and spyware can attack your smartphone or tablet via the following means:

· Downloading apps which are infected. These include apps which are downloaded from the device or operating system’s official store.

· Connecting your device to a computer, for example in order to install updates, sync and load music.

Viruses and spyware can cause very serious consequences including:

· Identity theft from apps working in the background to steal personal information stored on the tablet or the phone.

· Fraud from apps working in the background to steal personal information stored on the tablet or the phone.

· Premium rate calls and text messages being sent from your phone without your knowledge.

· Deletion and corruption of data.

· A slow or unusable device.

· Decreased battery life.

Your device could be just carrying a virus – which could then be passed on to other devices (such as computers) via email.

Protecting your Tablet and Mobile Device

You can install third-party apps and browsers to enhance security on your devices.

· Always check the security settings in your device to ensure maximum protection.

· Periodically check on your service provider’s website for updates for your make and model of smartphone or tablet.

Mind over Machine: Use Your Brain Waves to Control Your Computer

 

When it comes to controlling our computers, the last five years has seen incredible improvements in user interfaces including amazing touchscreens and much more natural vocal recognition. Now a Toronto company wants to take the UI to the next level—by going directly to the brain. You think it, and the Muse headband will make it happen under very limited circumstances.

InteraXon, the maker of the Muse headband, translates your mental commands into a computer action. The example it shows on the site is playing a game using an iPad, where the rotation of a wooden block occurs when the user focuses on it. The user tilts the iPad to change the angle of the rotation.

Muse sits across your forehead like a headband, and rests behind your ears like a pair of glasses. When properly worn, the EEG (electroencephalography) sensors on the front of the band make contact on your forehead, and the reference sensors on the arms rest on the backs of your ears. Muse connects wirelessly to your devices via Bluetooth.

The ideas behind the Muse are echoed in a project released by Chaotic Moon Studios earlier this year called the Board of Imagination, whereby a user controls a skateboard that’s connected to an iPad and a brain-wave reader made by a different company called Emotiv. In that case, the user’s focus is what makes the skateboard move forward.

The idea of a real brain-to-computer interface is cool and has been around for years. There are wonderful examples of people using their minds to control wheelchairs or even hooking prosthetic limbs into a person’s nervous system and then the person learns to control them using her thoughts. There is also similar research that could make an even more effective UI. But to turn our thoughts into something computers can understand—and perhaps make the most efficient UI of all—we need several things to happen:

1. Comfortable implementation—today it’s a headband or a helmet that reads brain waves from external EEG sensors, but to get to the subtleties that a true user interface would require we’d need to put sensors inside the head or add more components, such as the vision mentioned in the research above. But if we want to rely on the brain, then we need better electronics that could be implanted into a person’s body, which requires new coatings and research into chips and sensors that is ongoing. We also need to learn more about the brain.

2. A compelling use case for the UI to drive usage and adoption—you don’t already know how to work these interfaces; you have to learn how to focus in a way that the EEG readers can understand. The Muse may help in this regard, because by playing simple games, users can train their brains to focus in a way detectable by the EEG monitors. Some of the use cases even give people a brain score that shows how well they “focus.” Games and personal improvement apps seem like a good reason for people to adopt the technology and thus get it into the mainstream.

3. A set of standards for the hardware and implementation of a brain-wave database—a good UI platform should be like the keyboard or language recognition. There needs to be a consistent set of meaning for each thought across all platforms. So if there are three different brain-wave reading helmets on the market, you need to be able to control objects by using all of them the same way. That will speed adoption and the development of applications.

So, while the Muse is a cool project and may indeed usher in a new user interface, there’s plenty of other work going on in this realm and a lot more needs to happen. But when we consider the massive amounts of digital information we’re going to be negotiating in real time, the idea of some kind of computer-oriented telekinesis is pretty compelling.

"Jelly Bean" install base rising slowly, "Ice Cream Sandwich" growing faster

 

 

It’s time for the update on Android install bases again. It’s always interesting to see which versions of Android are growing, which ones are shrinking, and what percentage of Android owners are still hanging around with the old versions. The data from this report is generated based on devices accessing Google Play in a two-week period, which in this case is the period up to November 1. The story of this report is the incredibly slow growth of Jelly Bean, and the solid growth of Ice Cream Sandwich.

 


Jelly Bean is currently installed on 2.7-percent of Android devices, up from 1.8-percent a month ago. While not exactly numbers that are going to blow anyone out of the water, at least it’s growing. Ice Cream Sandwich actually went up 2.1-percent in the same period, up to 25.8-percent from 23.7-percent in the same time period.

It looks like a good portion of those upgrades came from Gingerbread, which dropped 1.6-percent. In spite of this drop, Gingerbread devices still hold well over 50-percent of the install base, making it by far the most used version of Android. Older version fell too, but by a lower number. Hopefully, the trend of devices updating will keep those ICS and Jelly Bean numbers climbing.

Moving towards newer OS versions has to come from device manufactures, but with the influx of new devices hitting the market all the time, it’s tough for device makers to keep up. For example, Sony announced that all of its pre-2012 devices would not receive Jelly Bean updates. Situations like that are obviously not going to help increase Jelly Bean installs. Either way, it’s still good to see that at least more devices are moving the way of ICS, even if Gingerbread is still dominating.

 

Parallax barrier technology

 

A parallax barrier is a device placed in front of an image source, such as a liquid crystal display, to allow it to show a stereoscopic image or multiscopic image without the need to wear 3D glasses.

The principle of the parallax barrier was independently invented by Auguste Berthier, who published first but produced no practical results, and by Frederic E. Ives, who made and exhibited the first known functional autostereoscopic image in 1901.About two years later, Ives began selling specimen images as novelties, the first known commercial use. Nearly a century later, Sharp developed the electronic flat-panel application of this old technology to commercialization, briefly selling two laptops with the world's only 3D LCD screen.

Parallax-barrier technology requires a barrier in front of a screen. The screen shows both the left and the right images, and the barrier effectively has slits in it that separate them out. If you look at it from exactly the right spot, the slits will allow the left image through to your left eye, and the right image through to your right eye, with no overlap.


So far the parallax barrier technology has mainly just been used for individual gaming on small, handheld screens. Because it requires you to sit in a specific position to get the 3D effect, it's not ideal for watching TV with your partner or friends.

But manufacturers do appear to be finding ways to increase the angle over which you can see a 3D image

What Are QR codes?

 

They come to us from Japan where they are very common. QR is short for Quick Response (they can be read quickly by a cell phone). They are used to take a piece of information from a transitory media and put it in to your cell phone. You may soon see QR Codes in a magazine advert, on a billboard, a web page or even on someone’s t-shirt. Once it is in your cell phone, it may give you details about that business (allowing users to search for nearby locations), or details about the person wearing the t-shirt, show you a URL which you can click to see a trailer for a movie, or it may give you a coupon which you can use in a local outlet.

QRCode

The reason why they are more useful than a standard barcode is that they can store (and digitally present) much more data, including url links, geo coordinates, and text. The other key feature of QR Codes is that instead of requiring a chunky hand-held scanner to scan them, many modern cell phones can scan them.

How does the cell phone read the code?

The cell phone needs a QR code reader, like this one from Kaywa. It takes literally 1 minute for someone with an iPhone or Android phone to find and install the reader.

How do you generate a code?

You can easily generate a QR code using a site like Kaywa.com or you can use the Open Source code to generate codes for you if you have a smart developer on hand. Google also has a tool — see our separate article about that:Close-Up With Google’s New QR Code Generator.

How can you use QR codes to benefit search marketing?

We are only just scratching the surface of how they will be used. We have added one to every business listing in our directory. Here are a few examples of how others are using them.

 

How could you use a QR code?

Your business, no matter how small or large, could use QR codes in a number of ways. You might auto generate one next to every product on your web site containing all the product details, the number to call and the URL link to the page so they can show their friends on their cell phone. You could add one to your business card containing your contact details so its easy for someone to add you to their contacts on their cell phone.

Add them to any print advertising, flyers, posters, invites, TV ads etc containing:

  • Product details
  • Contact details
  • Offer details
  • Event details
  • Competition details
  • A coupon
  • Twitter, Facebook, MySpace IDs
  • A link to your YouTube video

IPS Panel

Technology

Liquid crystal display (LCD) technology is classified into the three categories of TN, IPS and VA (in its different forms) depending on the liquid crystal driving method

IPS technology was developed by Hitachi in 1996 to solve the two main limitations of TN-matrices at the time, those being small viewing angles and low-quality color reproduction.

This technology like any other technology was first very expensive and due to the high cost involved it was used by very few people, most of them being graphic professionals.

Of course, over time, IPS was improved and refined, and as is the case with most new technologies, costs eventually came down to an acceptable level for mass-production.

The name In-Plane Switching comes from the crystals in the cells of the IPS panel lying always in the same plane and being always parallel to the panel’s plane (if we don’t take into account the minor interference from the electrodes). When voltage is applied to a cell, the crystals of that cell all make a 90-degrees turn.

IPS matrices differ from TN Film panels not only in the structure of the crystals, but also in the placement of the electrodes – both electrodes are on one wafer and take more space than electrodes of TN matrices.

IPS panels are also known as "8-bit panels" which means the panel can produce 256 shades of each primary color (Red, Green, Blue) using binary math. That means these panels can truly create 16.7 million colors. Nowadays many big companies in world for example LG, NEC, Phillips and Apple are using this technology in their products.


Advantages

  • IPS panels can process high speed signals without data loss by using copper wiring with low resistance values.
  • IPS Panels offer clear images and stable response time.
  • IPS panels display consistent and accurate color from all viewing angles.
  • IPS panels are suitable for graphic work & fast gaming.

· IPS panels do not lighten or show tailing when touched and are therefore ideal for interactive displays such as touch screens.

The Real Powerof Loud Speakers

Energy Sistem as a brand committed to music and to all the sensations aroused, recognizes the importance of loudspeakers power in sound quality. Therefore, in this guide, we are going to explain each level of power which is available in the market, in order to familiarize with most technical features and to get, in this way, a better confidence when choosing a sound system, according to our needs.

Generally speaking, we can say that the power is measured in WATIOS (W) and indicates, in some ways, the “strong” construction of loudspeakers. There are different ways of expressing the power depending on its manufacturer: continuous power (RMS) or peak power.

-CONTINUOUS POWER (RMS):

RMS means “Root Mean Square” indicates a statistical measure of the magnitude of varying quantity. This is the maximum radiated power that can be supported by the loudspeaker before distorting the sound in excess or is reaching the point of being deteriorated.

If the loudspeaker works exceeding this power rating, it will be damaged inevitably because it won’t be able to clear the heat produced by the electrical current that circulates through the coil and that one can melt the insulated copper coils.

This power measurement gives useful information when evaluating a sound system and can be useful as a comparator between different models. It is, definitely, the power which will work as a guide when deciding a purchasing because it is the most accurate and which gives much more value.

-PEAK POWER (PMPO):

The PMPO or “Peak Music Power Output” is the maximum power output. This term concerns the maximum power supplied and dissipated successfully to the loudspeakers, under perfect conditions. It is measured in extremely short time intervals (10ms) and until the loudspeaker will be break.

It is important to make clear that the power PMPO is not a “real” value. It is a commercial detail, totally useless, used by thousands of manufacturers, in order to have a strong argument in order to sell much more. Therefore, for a higher fidelity it is recommended to use power rating that represents the real power that the loudspeaker is able to support.

Android version history

Android version history

Android is a Linux-based operating system for mobile devices such as smartphones and tablet computers, developed by Google in conjunction with the Open Handset Alliance. Android, Inc. was founded in Palo alto, California, United States in October 2003 by Andy Rubin (co-founder of Danger), Rich Miner (co-founder of Wildfire Communications, Inc.), Nick Sears (once VP at T-Mobile), and Chris White (headed design and interface development at WebTV)

Android was initially developed by Android Inc, whom Google financially backed and later purchased in 2005. The unveiling of the Android distribution in 2007 was announced with the founding of the Open Handset Alliance, a consortium of 86 hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices.

An open standard is a standard that is publicly available and has various rights to use associated with it, and may also have various properties of how it was designed.

Google releases the Android code as open-source, under the Apache License. The Android Open Source Project (AOSP) is tasked with the maintenance and further development of Android.

Android has a large community of developers writing applications ("apps") that extend the functionality of the devices. Developers write primarily in a customized version of Java, and apps can be downloaded from online stores such as Google Play (formerly Android Market), the app store run by Google, or third-party sites. In June 2012, there were more than 600,000 apps available for Android, and the estimated number of applications downloaded from Google Play was 20 billion.

Android became the world’s leading smartphone platform at the end of 2010. For the first quarter of 2012, Android had a 59% smartphone market share worldwide. At the half of 2012, there were 400 million devices activated and 1 million activations per day.

What is UPS?

 

What is UPS?

An uninterruptible power supply, also uninterruptible power source, UPS or battery/flywheel backup, is an electrical apparatus that provides emergency power to a load when the input power source, typically the utility mains, fails. A UPS differs from an auxiliary or emergency power system or standby generator in that it will provide instantaneous or near-instantaneous protection from input power interruptions by means of one or more attached batteries and associated electronic circuitry for low power users, and or by means of diesel generators and flywheels for high power users. The on-battery runtime of most uninterruptible power sources is relatively short—5–15 minutes being typical for smaller units—but sufficient to allow time to bring an auxiliary power source on line, or to properly shut down the protected equipment.

While not limited to protecting any particular type of equipment, a UPS is typically used to protect computers, data centers, telecommunication equipment or other electrical equipment where an unexpected power disruption could cause injuries, fatalities, serious business disruption or data loss. UPS units range in size from units designed to protect a single computer without a video monitor (around 200 VA rating) to large units powering entire data centers, buildings, or even cities.

What is E-Ink Technology ?

 

What is E-Ink Technology ?



Ink invention is attributed to the Chinese –which have invented it 2500 years B.C in order to remain stories captured-. Nowadays, the ink has the same purpose; but it is not made by natural and digital dyes but with spheres charged electrically in order to display letters on a screen without glare –which can be read under the sun or even adjust it as we want.

Ten years ago when university scientists at the USA have started to work on a futurist project that today is reality. It was not a bad idea to replace the paper that came from centuries ago for ultramodern screens – with a card thickness and, of course, portable-. They had started working at that time and today –ten years later- they are already for sale at an affordable price .

The screen is formed by thousands of small balls electrically charged –the half was on white and the other half on black-. Besides being unfinished painted –each hemisphere have different polarity-. When they are activated and depending on the position of the thousands of those spheres situated on the page, they start forming letters, words, paragraphs… Simple but effective –and the best is its own electric consumption which allows the battery life of all devices even for weeks!

However, the electronic reading has loads of aspects to improve in our society –as the vegetable-based inks that from its beginning was hard to set up at school’s inkwells, offices from the beginning of the XX century –when they were the only option to write. Then, we have passed to rechargeable and disposable pens, later to ink cartridges for typewrites and the giant leap was to the printer cartridge. As consumers, we have to take the decisive leap forward to accept that it has already arrived to stay, because that will be the only device for reading.

The opened and perpetual invitation is focused not only on the consumer and book reader –they just have to be persuaded and convinced to try it- but also on the teachers and students. In order to implement creatively and introduce E books at school because it is the reading epicentre in our society, and it is where the revolution and change will be really gestated.

Besides, the use of those E books will allow taking off weight from the school bags, reducing the cost of the school equipment in the medium term. Contributing the environment and providing the benefits to adjust font size to hundreds of thousands of students with reading deficiencies, which will take advantage from the beginning of the most comfortable and adaptable reading adjusts, and of course, of the ethical values of sharing books and documents immediately. The main objective pursued is the more efficient transmission of knowledge suited to our times.

They are several different schools and universities in the whole world which have accepted E Ink devices as a reading support. The most important bookstores and publishing companies have been added to the online sale of books –which guarantees the availability of each book around the world and which also reduces costs-. Therefore, the figures showed that the consumption of E Books has increase by 220%; it is the same figure for the sales of devices.

Whatever time of the year is propitious to get your first eReader. Energy Sistem has the most completed catalogue of the market –from E Ink devices to the TFT colour screen- do not wait any longer and be seduced by captivate stories, short stories, novels, tales, comics, which are waiting to be discovered under hundred of reading benefits with an electronic reader.

A book will always be the best present and now as a complement we have the eReader, instead of acquiring it on our trusted bookshop, without leaving home or your office; and download on a few seconds your Energy Sistem e Reader, the Best Seller or the best book of your favourite author and favourite writer.
