What is CPU?

In this generation, everyone knows about Computers. But they don't know about the components of the computer in detail. 

CPU (central processing unit) is not the iron cabinet, it is more that it. CPU is a processing device that is used to do manage every process during working. When the user provides an input to the computer, the CPU takes the process as input and work on it (process) and then provide output. 

In the above picture, you can see the CPU. As we know CPU manages every process of the computer that why CPU also is known as Processor or Micro-Processor.

The processor or CPU divided into three parts:-

1. CU (Control Unit):- Control unit control every processing and devices that are connected to the CPU. And also work for the real-time update, decision making, inputs, outputs everything controlled by the CPU or Processor.

2. ALU (Arithmetic and Logic Unit):- Arithmetic and Logic unit control every process that is related to the calculation or mathematics solution like- addition, subtraction, multiplication, division, etc. and also work for a logical process like- if, else, equals, NOT, AND, etc.  

3. MU (Memory Unit):- Memory unit is not inbuilt in the CPU or processor. Memory unit directly attached to the CPU. All of the processing, inputs, outputs are stored into the memory unit. If the user does not attach the memory unit with the CPU, the computer will not start or boot.
