Initially bit - a characteristic of the computer's CPU, which determines the amount of information they processed in one clock cycle.This setting affects performance system and the ability to use the processor more advanced hardware.To take full advantage of the hardware capabilities, and created software that specialize in working with "iron" a certain bit.Learn bit operating system possible means the OS itself.
- of Windows.
