On the basis of working mode:
Analog computer
Digital computer
Hybrid computer
Analog computer:
An analog computer is one that measures physical values such as temperature, pressure, humidity etc. The analog computer accepts processes and generates continuous data. One major use of analog computers has been as control device on a real time scale, for example the navigation of controlled rockets or factory automation.
Some examples: mechanical integrator, MONIAC computer, analog speedometer of bikes and car etc.
Digital computers:
A digital computer accepts processes and produces discrete data. It uses 0’s and 1’s for processing any information. They are extremely popular science they are faster and more accurate in calculation than analog computer. Modern digital computers find extensive use in scientific, business, administration and engineering applications, industrial application, airline railway reservation, education, medicine and many more.
Hybrid computers:
Hybrid computers are those computers which combine analog and digital capabilities in a single computer. Hybrid computers are used for some special application. It is the combination of both analog and digital computers. The digital component normally serves as the controller and provides logical operation, while the analog component normally serves as a solver of differential equation.
Example: HRS-100
On the basis of size:
Micro-computer:
Generally a computer that resides in user’s desktop is called a micro computer. Micro computer include PC’s, laptops, notebooks and handheld computers or palmtop computers. Example desktop PC, laptop etc.
Mini computer :
These computers are larger then micro computers and these computers are 3-25 times faster then micro computers. Example: prime 9755, vax 36 etc
Mainframe computer:
These computers are larger then mini computers and there processing speed is 10-100 times faster then micro computers. Example: IBM 1401, ICL 2950/10 etc.
Super computer:
These computers are larger in size and are most powerful computers and can process at a speed of several hundreds or even thousands of millions of instruction per second. Example: NEC 500, cray-xmp-14 etc.
