Diffrence Hi ,,, please tell me what is the difference between Windows 32-bit and 64-bit and this icreament affact on what ??? thank you

Please allow me to explain it in a non technical way. if you wish to have it in a technical way please visit the ref site below.
these are computer grades(platforms) that differentiates computer speeds. 32-bit computer takes 32bits of data each round it transfers. 64- bit takes 64bits of data each round.hence 32-bit trasfers twice the same data that 64-bit transfers once.therefore a 64-bit computer remains faster than 32-bit.

Simple answer. 64 bit allows you to use more than 4 gb RAM and sees it all. 32 bit will only recognize a little over 3 GB RAM so if you have more it is basically reserved for Windows itself. 64 bit does allow better use of system resources as well. But in order to run 64 bit you need a cpu that is compatible. Most of the newer dual core cpu's as well as all quad core cpu's can run Windows 64 bit. Hope this helps explain it a little better for you.

The terms 32-bit and 64-bit refer to the way a computer's processor (also called a CPU), handles information. The 64-bit version of Windows handles large amounts of random access memory (RAM) more effectively than a 32-bit system.
