Central Processing Unit (CPU)

The part of the computer that executes program instructions is known as, the processer or central processing unit (CPU). In a microcomputer, the CPU is based on a single electronic component. The microprocessor chip, within the system or system cabinet. The system unit also include circuit boards. Memory chips, ports, and other components.

The CPU has two parts---the control unit (CU) and the Arithmetic logical unit (ALU). In a microphone

Both are the microprocessor chip.

Cantrol Unit (CU)

The control unit tells the rest of the computer system how to carry out the programme instructions. It directs the movement of electronic signals b\w memory – which temporaily holds data, instructions and processed information – and the ALU. It also direct these cantrol signals b\w The CPU and input\output devices
