Xiaobian to share with you what are the five major parts of the computer, I believe most people do not know how, so share this article for your reference, I hope you have a lot of harvest after reading this article, let's go to understand it together!

The five components of a computer are controller, arithmetic unit, memory, input device and output device. CPU, memory and hard disk are the three core components of computer. CPU is mainly used to control the system, memory is used to access data, input devices and output devices are collectively referred to as I/O.

The five major components of a computer include: controller (CU), arithmetic unit (ALU), memory (Memory), input device (Input) and output device (Output).

Three core components of computers:

CPU, memory and hard disk.

CU is mainly control system, ALU's function is to carry out mathematical operations and logic operations;

CPU=ALU+CU。

In human organs, similar to the human brain. Memory is equivalent to human memory (temporary access), while hard disk is equivalent to a notebook (permanent storage).

Memory is divided into internal memory and external memory.

The advantage of memory is that access speed is faster than hard disk; the disadvantage is that power failure data is easy to lose and cannot be saved.

The advantage of external hard disk is that the data will not be lost after power failure and can be permanently preserved; the disadvantage is that the access speed is slower than that of memory.

Input devices: keyboard, mouse, touch screen

Output devices: monitors, stereos, printers

Input devices and output devices are collectively referred to as I/O.

The above is "What are the five parts of the computer" all the content of this article, thank you for reading! I believe that everyone has a certain understanding, hope to share the content to help everyone, if you still want to learn more knowledge, welcome to pay attention to the industry information channel!
