Answer 3

The basic diff b/w 32 and 64 bit OS are the size of the integer and the size of the pointer (32/64 bit).

Answer 4

There are a few differences between the two types. x64 can run twice as many colours than x32, giving a much better looking image than you would be used to. Also, performance-wise, x64 is much faster than x32, and the difference is immediately noticable. Besides that, on an x32 system, the max amount of RAM that can be installed is 4GB, whereas on Vista Ultimate x64, you can have 128GB.

The main disadvantage of x64 (on XP mainly though) was that alot of programs still aren't compatible, deciding to stay with x32 for a little while longer. But seeing as Vista is primarily an x64 system, that problem won't be around much longer.

Hope that helps=]
