Mainframe Computers 

These computers are larger in size and more costlier than Mini Computer. They have large internal storage. Also know as backbone of business world. Examples of Mainframe computers are - IBM-370, IBM-S/390, UNIVAC-1110 etc.

Super Computers 

These computers are fastest and most expensive computer in the world used for whether forecasting, business application, scientific and nuclear research. They have much speed that is measured in FLOPS ( Floating point operation per second). PARAM was the first super computer made by India by organization C-DAC.

According to work computers are categorized below:-

Analog Computers 

These computers work on continuous electrical pulses can carry out arithmetic and logical operations. used in speedometers and seismograph. 

Digital Computers 

These computers are work on binary digits used to perform mathematical problems to produce desired result. 

Hybrid Computers 

These computers are the combination of analog and digital computer, used in hospitals for ECG (Electrocardiography) and DIALYSIS.
