Windows Vista 64 & 32 Bit Difference?

[Farmer]

What is the difference between 32 bit and 64 bit Vista?

[JAMES_911]

IMO there is no difference between these two versions other than the support for various programs.

The basic difference is that a 32-bit process process 32 bits at a time whereas 64-bit processes 64 bit at atime...
Its like say there is a passage ..Through one passage 32 peoples can pass at the same time ...On the other hand there is a passage by which 64 peoples can go same time.

So 64 bit processes twice the speed than that of 32 bit

The terms 32-bit and 64-bit refer to the way CPU handles information. The 64-bit version of Windows handles large amounts of random access memory more effectively than a 32-bit system.
