*Types of computer;-
Computer is a high speed electronic device. It is classified into three categories,such as-
1.Analog computer
2.Digital computer
3.Hybrid computer
1.Analog computer;- It search a computer where qualify information convert into contify information ,such as- Temperature, Presser, Length and Weight etc.
2.Digital computer;- This computer convert the data into digit then count the number, such as- letter number or special symbol . There are four types of digital computer.
I. micro computer
II. mini computer
IV. mainframe computer
V. super computer
