in this types computer are very small. in this computer microprocessor was used so its called micro computer example IBM pc. Desktop computers, laptops, personal digital assistant , tablets & smartphones are all types of microcomputers.
These computers are the cheapest among the other three types of computers. The Micro-computers are specially designed for general usage like entertainment, education and work purposes. Well known manufacturers of Micro-computer are Dell, Apple, Samsung etc.
It’s size is grater then Micro and less then mainframe computer. Minicomputers are used by small businesses and firms.

It is very big in size.Supercomputer is the fastest computers currently available. Supercomputers are very expensive. These computers are employed for specialized applications that require immense amounts of mathematical calculations (number crunching).Super computer are using for scientific reason as like space laboratory for controlling as a rocket launcher
Param is a example of this type
Computer are 3 types according Working place
- Analog Computer-:An analog computer is a form of computer that uses continuous physical phenomena such as electrical, mechanical etc.
- Digital Computer-: A computer that work for in big range as like calculation and operation in big range this types computer use.
- Hybrid Computer-: in this type computer inputting and outputting both the signal analog and digital are using.
Computer are 2 types according of use
1.Simple Computer-: This type computer are making for a simple purpose as like personal computer, That we can use for personal purpose in the home,office or business purpose.
2.Special Computer: This type computer are using very special purpose computer as like laboratory ,space laboratory etc. For example of this type computer is super computer etc.
