How i understand in Windows differences between 32 and 64 bits is that 64 can see more than 3GB Operation Memory, and how i read on many forums there says that 64bit work faster, but all recommend 32bit, why ? If 64bit can see more memory, work faster, then why still there is 32bit, and why some people recomemnd 32bit for Ubuntu instead of 64 ?

Answer 1

stability, better software and drivers in general, also many 64 bit programs are just a "raw" porting from their 32 bit counterpart.

Unlike what many people think, a 32 bit kernel has no problem in managing more than ~4 Gb of RAM, infact enterprise-grade 32 bit solutions can use PAE kernels that work just fine.

Regarding Windows 32 bit desktop the answer is simple: it's licensed that way, so the user can't use more than ~3.5Gb of RAM because the OS was built and shipped with that limitation.
