Those three types of computers are
- Analog computers
- Digital Computer
- Hybrid Computer
- Analog computer
Analog computer is a computing device that works on Continuous rang of value.the result given by the analog computer will only be approximate since they deal with quantities that very continuously.It generally deals with physical variable such as voltage,pressure,temperature,speed,etc.2.Digital Computer
On the other hand a digital computer operates on digital data such as number.It uses binary number system in which there are only two digits 0 and 1.1 is called a bit.
The digital computer is designed using digital circuits in which there are two levels for an input and output signal.These two levels are know as logic 0 and logic 1 .Digital computers can give more accurate and faster results.
Digital computer is well suited for solving complex problems in engineering and technology .Hence computer have an increasing use in the field of design,research, and data processing.
Based on the purpose.Digital computers can be further classified as,
- General purpose Computers
- Special Purpose of Computers
3.Hybrid Computer
A hybrid computer combines the desirable features of analog and digital computer.It is mostly for automatic operations of complicated physical processes and machines.Now-a-day analog-to-digital converters are used for transforming the data into suitable form for either type of computation.
Types of computers based on configuration
There are different four types of computers when we classify them based on their performance and capacity.
The four types are
- Super computers
- Mainframe computers
- Mini computers
- Micro computers
