The CPU interprets instructions and performs logical and arithmetic operations to control the computer. It follows a machine cycle of fetching instructions from memory, decoding them, executing the operations, and storing results. The CPU consists of a control unit that manages resources and a machine cycle, and an ALU that performs arithmetic and logical functions according to the control unit's instructions.

- How fast a cpu can execute instructions depends on its internal clock called system clock and measured in number of ticks or cycles per second, usually MHz or GHz Clock speeds of 2 GHz and more are now available Word size depends on the size of registers, 8bit, 16 bits, 32 and now 64 bits
