Step-by-step explanation:
Analog computers:
An Analog computer is a computing device that works on a continuous range of values. The results given by the analog computers will only be approximate since they deal with quantities that vary continuously. It generally deals with physical variables such as voltage, pressure, temperature, speed, etc. Results generated by these computers are not complete, there may be any fractions values involve with the results of these computers, wall clocks are the main example of this computer.
Digital computer:
On the other hand, a digital computer operates on digital data such as numbers. It uses binary number system in which there are only two digits 0 and 1 each one is called a bit.
The digital computer is designed using digital circuits in which there are two levels for an input or output signal. These two levels are known as logic 0 and logic 1. Digital computers can give more accurate and faster results. A digital computer is well suited for solving complex problems in engineering and technology. Hence digital computers have increasing use in the field of design research and data processing. Based on the purpose, digital computers can be further classified into two main categories
General purpose computers
Special purpose computers
Hybrid computer:
A hybrid computer combines the desirable features of analog and digital computers. It is mostly used for automatic operations of complicated physical processes and machines. Now a day’s analog to digital and digital to analog converters are used for transforming the data into suitable form for either type of computation
For example, in hospital ICU analog devices might measure the patients temperature, blood pressure, and other vital signs. These measurements which are in analog might then be converted into numbers and supplied to digital components. In the system these components are used to monitor the patients vital sign and send signals if any abnormal readings are detected, hybrid computers are mainly used for specialized tasks.
