Question

Difference between Vista 32 bit and Vista 64 bit please.?

Answer 1

32-bit Vista is meant to work on 32-bit CPU's and the 64-bit Vista is for 64-bit CPU's.

The 32-bit version of Vista runs on both CPU's.

On computer stores today you mostly find 64-bit laptops with 32-bit Vista. This is not the best OS for the laptop but since very few companies make drivers for 64-bit Vista, you have not other choice.

64-bit drivers you need are for Webcam, Wifi, fingerprint reader, bluetooth, usb, firewire, ethernet, graphics card, etc.

64-bit Vista is usually a headache. 64-bit Windows Server 2008 you might think is better but no, it is even worse in that regard.

Answer 2

Vista 32 is designed for use on 32-bit architectures (P4 or Athlon and lower).

Vista 64 is designed for use on 64-bit architectures (Intel Core or Athlon 64 and higher)

64-bit architectures are 32-bit backwards compatible. You can run 32-bit programs and operating systems on 64-bit hardware.

32-bit architectures are NOT compatible with 64-bit software or operating systems.

32-bit architectures have a hard RAM limit of 4GB. 64-bit architectures have a soft limit of several TB, and a hard limit of 16EB (16.8 million TB or 17.2 billion GB) of RAM.

Answer 3

The difference between 32 and 64 bit has to due with how the os accesses memory.

How it affects you is that it will run faster, but there is a chance that older programs will not be compatible.
