Classification based on Operating Principles
Based on the operating principles, computers can be classified into one of the following types: -
A. Digital Computers
B. Analog Computers
C. Hybrid Computers
Digital Computers: - Operate essentially by counting. All quantities are expressed as discrete or numbers. Digital computers are useful for evaluating arithmetic expressions and manipulations of data (such as preparation of bills, ledgers, solution of simultaneous equations etc)
Analog Computers:- An analog computer is a form of computer that uses the continuously changeable aspects of physical phenomena such as electrical, mechanical, orhydraulic quantities to model the problem being solved. In contrast, digital computers represent varying quantities symbolically, as their numerical values change.
Hybrid Computers:- are computers that exhibit features of analog computers and digital computers. The digital component normally serves as the controller and provides logical operations, while the analog component normally serves as a solver of differential equations.
