Mention and explain different units of CPU (Central Processing Unit).

A typical CPU has a number of components. The first is the arithmetic logic unit (ALU), which performs simple arithmetic and logical operations. Second is the control unit (CU), which manages the various components of the computer.

CPU (Central Processing Unit) is electronic circuitry - the basic computation unit of the computer, that performs the basic arithmetic, logical, control and input/output (I/O) operations. There are two main types of CPU according the producer: Intel (Celeron, Pentium and Core) and Advanced Micro Devices (AMD). Intel makes mobile processors for notebooks.
