The CPU is the part of a computer that controls the operation of the computer. All arithmetic and logical operations, decoding of instructions and the execution of instructions are performed by the CPU. Early computers used several chips to handle the task. Some functions are still handled by support chips, which are often referred to collectively as a chip set.
