What’s the difference between 32-bit and 64-bit?

What’s the difference between 32-bit and 64-bit? -The term “bit” is short for “binary digit,” which can be a 1 or 0.

In this context, the number of bits refers to how many 1’s and 0’s the computer’s processor can use to communicate instructions and assign memory addresses.

32-bit processor

The 32-bit processor was the primary processor used in all computers until the early 1990s. Intel Pentium processors and early AMD processors were 32-bit processors. The Operating System and software on a computer with a 32-bit processor is also 32-bit based, in that they work with data units that are 32 bits wide. Windows 95, 98, and XP are all 32-bit operating systems that were common on computers with 32-bit processors.
64-bit processor

The 64-bit computer has been around 1961 when IBM created the IBM 7030 Stretch supercomputer. However, it was not put into use in home computers until the early 2000s. Microsoft released a 64-bit version of Windows XP to be used on computers with a 64-bit processor. Windows Vista, Windows 7, and Windows 8 also come in 64-bit versions. Other software has been developed that is designed to run on a 64-bit computer, which are 64-bit based as well, in that they work with data units that are 64 bits wide.

The main difference between 32-bit processors and 64-bit processors is the speed they operate. 64-bit processors can come in dual core, quad core, and six core versions for home computing (with eight core versions coming soon). Multiple cores allow for increase processing power and faster computer operation. Software programs that require many calculations to function operate faster on the multi-core 64-bit processors, for the most part. It is important to note that 64-bit computers can still use 32-bit based software programs, even when the Windows operating system is a 64-bit version.

Another big difference between 32-bit processors and 64-bit processors is the maximum amount of memory (RAM) that is supported. 32-bit computers support a maximum of 3-4GB of memory, whereas a 64-bit computer can support memory amounts over 4 GB. This is important for software programs that are used for graphical design, engineering design or video editing, where many calculations are performed to render images, drawings, and video footage.

One thing to note is that 3D graphic programs and games do not benefit much, if at all, from switching to a 64-bit computer, unless the program is a 64-bit program. A 32-bit processor is adequate for any program written for a 32-bit processor. In the case of computer games, you’ll get a lot more performance by upgrading the video card instead of getting a 64-bit processor.

In the end, 64-bit processors are becoming more and more commonplace in home computers. Most manufacturers build computers with 64-bit processors due to cheaper prices and because more users are now using 64-bit operating systems and programs. Computer parts retailers are offering fewer and fewer 32-bit processors and soon may not offer any at all.

also 32 bit windows are restricted to only 3gb ram
but if you have 4 gb ram or more then you have to install 64 bit windows to complete use your memory.

32-bit and 64-bit Windows: frequently asked questions

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.
