1. Digital Computer
Digital computers work upon discontinuous data. They convert the data into digits(binary digits 0 and 1) and all operations are carried out on these digits at extremely fast rates. A digital computer basically knows how to count the digits and add the digits. Digital computers are much faster than analog computers and far more accurate. Digits computers are the most versatile machines in the electronic family. They perform calculations by counting. There are mainly two types of digital computer:-
• Special-purpose computer
• General-purpose computer

2.Analog Computers
In analog computers, continuous quantities are use .in other words, analog computers measure, representing numbers by physical magnitudes such as voltage, temperature and pressure. The devices that measure such quantities are analog devises, e.g., odometer, speedometer, voltmeter, ammeter. Analog computers operate by measuring rather than counting.

3.Hybrid Computers
A hybrid computers is a combination of both analog and digital computers i.e. it can perform functions of both a digital and an analog computer, For example, in an intensive care unit of a hospital, analog devices measure the patient’s heart function, temperature, or other vital signs. These measures are then converted into numbers or digits and supplied to a digital component that monitor.
