Is there a big difference?

And what is the difference between a 32 and a 64 bt OS? Is there a big difference?
32 bit is based round code where each part of the code is made of 32 0s or 1s, 64 bit uses 64 1s or 0sbasically if you have to ask then you don't need it, 64 can handle more RAM though has compatibility issues with older programsIs there a big difference?
[QUOTE=''milosbeli'']And what is the difference between a 32 and a 64 bt OS? [/QUOTE]With a 64 bit OS, you can use more than 2 GB of RAM, cause if you have say 4 GB in Windows XP 32-Bit, you can really only use 3 GB of it cause the OS only sees 3 GB. However the 32 bit versions of both windows XP and Vista are better at the minuite cause there are serious compatibility issues with the 64 bit versions when it comes to older games and the vast majority of software and utilities written today, which are mostly compatible only with the 32-bit versions. New titles woirk with the 64 bit versions, and the increased speed etc in intensive photo/video editing apps with a 64bit OS and the change the industry'll go through to 64-bit in the next few years it's good to have a copy around for the future upgrade, but right now, added to which most software/games are perfectly happy with 2 GB RAM, you should stick with a 32-bit OS
