Types of Computer | Micro, Mini, Main Frame and Super Computer

Types of Computers:

There are different types of computer available in the market used in various organizations as per requirement and demand. SOme of the types are:-

  1. Micro Computer
  2. Mini Computer
  3. Main Frame Computer
  4. Super Computer

Micro Computer:

In micro computer, CPU consists of a microprocessor (IC). It consists of system unit, input device, output device, secondary storage and communication.

Its processing speed is near about 1 lakh process per second. Some example of micro computers are: Desktop/PC, Laptop, Notebook, Tablets, Smartphone, Net book (Ipad & Chromebook), PDA (Personal Digital Assistance).

These computers are used in homes, business, entertainment, medicine etc.

 

PDA COmputer

 

PDA(Personal Digital Assistance) is that computer which is small in size with screen and keyboard facility used in 90’s to 20’s. PDA also known as Palm top or Palm Computer.

Check out some Personal Computers:

 

Mini Computer:

This computer works on multiuser application where 100 to 150 users work simultaneously. Mini Computer can be converted into super mini computer by using the 80836 super chips.

It is used in Industries, Researches (High Storage and Processing). Some examples: IBM 17 DEC, PDP-11, HP-9000 etc.
