Replacement for the older x86 or 32-bit platform, 64-bit is a computer or software program that is capable of transferring 64-bits at a time. With respect to hardware, 64-bit is referencing the width of the registers on a computer's microprocessor or the computer bus; sometimes called WOW64 and x64.
