(a) Analog Computer:
The computers that use signals as input are called analog computers. The signals are the temperature, pressure, speed, etc. Signals flow continuously in these computers. However, signals can also be fed in these computers for the purpose of processing. The examples of analog computers are thermometer, speedometer, etc.
(b) Digital Computers:
Digital computers accept digits and alphabets as inputs; therefore, these are called digital computers. For example, computers used in business purpose are digital computers because data are inserted in the form of digits and alphabets.
(c) Hybrid Computers:
Variations are found in methods of applications. If you want to observe the variation in signals, it becomes rather difficult. Because variations in signals are very small that is why these cannot be checked manually.
But the action is to be taken very fast. It makes impossible for a man to act within the required time. Now it can be done by hybrid computers which deal with such applications.
Hybrid computers require two types of inputs: (i) signals of which variations are to be monitored, and (ii) instructions for monitoring and doing the actions. Instructions are in the form of digits and alphabets. Therefore, hybrid computers use signals, digits and alphabets as input.
For example, levels of radioactivity in an atomic reactor are measured by a computer. A hybrid computer needs the level of radioactivity as input i.e. signal. In computer instructions are given in the form of digits and alphabets the basic arithmetic and logical operation in the memory. Thus, they are very versatile in performing the functions.
