32-bit and 64-bit Windows


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  version of Windows?


Windows Vista:

  1. Open System by clicking the Start button [image], right-clicking Computer, and then clicking Properties.

  2. Under System, you can view the system type.

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.




Refers to the number of bits that can be processed or transmitted in parallel, or the number of bits used for single element in a data format. The term is often applied to the following:


  • microprocessor: indicates the width of the registers. A 32-bit microprocessor can process data and memory addresses that are represented by 32 bits.
  • bus : indicates the number of wires in the bus. A 32-bit bus transmits 32 bits in parallel.
  • graphics device, such as a scanner or digital camera : specifies the number of bits used to represent each pixel. Typically 24 bits are used for color and the remaining 8 bits are used for control information.
  • operating system: refers primarily to the number of bits used to represent memory addresses.

    usually located at the bottom of the Windows screen, although it can be repositioned. It contains:


    • The Start button.
    • Various optional toolbars, such as the Quick Launch toolbar, which provides one-click access to frequently used programs.
    • Buttons for any open programs.
    • And, the notification area, which includes the clock icon plus icons for various system tools and utilities. You can interact with these utilities in various ways by clicking or right-clicking the icons.


     x86 is a generic name for the series of Intel microprocessor families that began with the 80286 microprocessor. This series has been the provider of computing for personal computers since the 80286 was introduced in 1982. x86 microprocessors include the 386DX/SX/SL family, the 486DX/SX//DX2/SL/DX4 family, and the Pentium 3 family. The x86 line replaced Intel's previous series, the 8086/8088. Adopted by IBM for its first PCs, the 8086/8088 and the continuing x86 series have made Intel the predominant force in microprocessor design and manufacture.
