Central processing unit is main part of computer. It is the brain of computer. A CPU(central processing unit)CPU) is electronic circuit. Basically central processing unit (CPU) has main two units. In short central processing unit (CPU) called processor. 

1) arithmetic logical unit(ALU):-It help us to calculate ma thematic solution.

2) control unit(CU):- It control all operation of computer include input/output (I/O. In early time there has been used the "central processing unit" at least since the early 1960s. most CPU are microprocessor, That means connected on a single integrated circuit (IC) chips. An IC contain a CPU may also related with computer memory, peripheral devices and other component of a computer. Some computers employ signal-core which is a single chips containing only one CPUs and multi-core Processor which is a single chips containing two or more CPUs that is called called "multi-core".
