LED or LCD displays ????

LED-backlit LCD TVs differ from conventional CCFL-backlit LCD TVs in the following:

• They can produce an image with greater dynamic contrast compared with CCFL-backlit LCD TVs. 
• With Edge-LED lighting they can be extremely slim. Current models on the market can be approximately one inch thick. 
• They can offer a wider color gamut, especially when RGB-LED backlighting is used. 
• Lesser environmental pollution on disposal. 
• Higher cost due to current market product placement. 
• Generally have a lower power consumption in the realm of 20-30%. 

              LED-backlit LCD TVs are considered a more sustainable choice, with a longer life and better energy efficiency than plasmas and conventional LCD TVs.  Unlike CCFL backlights, LEDs also use no mercury in their manufacture. However, other elements such as gallium and arsenic are used in the manufacture of the LED emitters themselves, meaning there is some debate over whether they are a significantly better long term solution to the problem of TV disposal.
                Because LEDs are able to be switched on and off more quickly than CCFL displays and can offer a higher light output, it is theoretically possible to offer very high contrast ratios. They can produce deep blacks (LEDs off) and a high brightness (LEDs on), however care should be taken with measurements made from pure black and pure white outputs, as technologies like Edge-LED lighting do not allow these outputs to be reproduced simultaneously on-screen.

32-bit and 64-bit Windows !!!! What is this man ?

What is the difference between 32-bit and 64-bit versions of Windows?

The terms 32-bit and 64-bit refer to the way a computer's processor (also called a CPU), handles information. The 64-bit version of Windows handles large amounts of random access memory (RAM) more effectively than a 32-bit system.

How can I tell if my computer is running a 32-bit or a 64-bit version of Windows?

To find out if your computer is running a 32-bit or 64-bit version of Windows in Windows 7 or Windows Vista, do the following:

1. 
   
   Open System by clicking the Start button , right-clicking Computer, and then clicking Properties.
2. 
   
   Under System, you can view the system type.

If your computer is running Windows XP, do the following:

1. 
   
   Click Start.
2. 
   
   Right-click My Computer, and then click Properties.
   • 
     
     If you don't see "x64 Edition" listed, then you're running the 32-bit version of Windows XP.
   • 
     
     If "x64 Edition" is listed under System, you're running the 64-bit version of Windows XP.

Which version of Windows 7 should I install: the 32-bit version or the 64-bit version?

To install a 64-bit version of Windows 7, you need a CPU that's capable of running a 64-bit version of Windows. The benefits of using a 64-bit operating system are most apparent when you have a large amount of random access memory (RAM) installed on your computer, typically 4 GB of RAM or more. In such cases, because a 64-bit operating system can handle large amounts of memory more efficiently than a 32-bit operating system, a 64-bit system can be more responsive when running several programs at the same time and switching between them frequently.

Microsoft Surface

What is Microsoft Surface?

Microsoft Surface is a revolutionary multi-touch computer that responds to natural hand gestures and real-world objects, helping people interact with digital content in a simple and intuitive way. With a large, horizontal user interface, Surface offers a unique gathering place where multiple users can collaboratively and simultaneously interact with data and each other.

The Microsoft Surface platform

Microsoft Surface is more than a computer. It’s a leap ahead in digital interaction. By enabling you to use your hands instead of a keyboard and mouse, it revolutionizes the way you interact with digital content, while keeping the ability to connect with other devices such as networks, printers, mobile devices, card readers, and more. Our Microsoft Surface Partners have created hundreds of applications for the platform.

Microsoft Surface is currently based on the Windows Vista platform, which makes it especially easy for companies to manage, deploy and support Microsoft Surface units. The current version for the software platform is Microsoft Surface 1.0 Service Pack 1, which enhances Surface with an enhanced user interface, improved manageability to help reduce the cost of ownership, broader international support, and faster, easier ways to design innovative applications. Read more about Service Pack 1 on the Microsoft Surface Blog.
