CLASSIFICATION You know that device, which computers is called computer. For computation, computer takes some input, performs computation on it and gives result. The type of input that computers accepts, decides its nature and capabilities and the type of computation that it will be able to perform. For example, some of the computers accept input in the form of signals. On the other hand, majority of computers take input in the form of digits. Some computers accept input in both the forms i.e. in the form of digits and signals. On the basis of input type, computers have been classified into following three categories: Analog computers Digital computers Hybrid computers A brief description is of all these types of computers is given below: Analog Computer Let’s first understand what is signal. Signal can be defined as continuous flow of physical identity. Temperature, pressure, water level, speed, voltage, current etc. are few examples...
