Difference between 32 and 64 bit Windows

32 bit

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, which means the operating system and software work with data units that are 32 bits wide. Windows 95, 98, XP are all 32-bit operating  systems. But later on this also work on windows vista and window 7.

Note: A computer with a 32-bit processor cannot have a 64-bit version of an operating system installed. It can only have a 32-bit version of an operating system installed.

64-bit processor

The 64-bit computer has been around since 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 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.

Note : A computer with a 64-bit processor can have a 64-bit or 32-bit version of an operating system installed. However, with a 32-bit operating system, the 64-bit processor would not run at its full capability.

Note: On a computer with  a 64-bit processor, you cannot run a 16-bit legacy program. Many 32-bit program will work with a 64-bit processor and operating system, but some older 32-bit programs may not function properly, or at all, due to limited or no compatibility.

Advantage of 64-bit

1-Using 64-bit one can do a lot in multi-tasking, user can easily switch between various applications      without any windows hanging problems.

2-Gamers can easily plays High graphical games like Modern Warfare, GTA V, or use high-end              softwares like photoshop or CAD which takes a lot of memory, since it makes multi-tasking with        big softwares easy and efficient for users. However upgrading the video card instead of getting a        64-bit processor would be more beneficial.

Remember—A computer with a 64-bit processor can have a 64-bit or 32-bit version of an operating system installed. However, with a 32-bit operating system, the 64-bit processor would not run at its full capability.
