Introduction to Programming

Main Parts of Computer: Computer is made of different parts.

CPU

CPU or Central Processing Unit is the brain of computer. It is very good at doing one work at a time and at a very fast speed. 

RAM

RAM or Random Access Memory is the memory of computer to store things it wants for some time.

Devices

You can connect different types of devices to Computer such as Monitor, Mouse, Keyboard, Printer, Speakers, Headphones etc. These devices can be of Input types such as Mouse, Keyboard, and Mics, or of Output types such as Monitor, Printer etc. Some devices can work as Input and Output both.
