Types of ComputerWe can categorize computer in two ways: on the basis of data handling capabilities and size.On the basis of data handling capabilities, the computer is of three types:Analogue ComputerDigital ComputerHybrid Computer1) Analogue ComputerAnalogue computers are designed to process analogue data. Analogue data is continuous data that changes continuously and cannot have discrete values. We can say that analogue computers are used where we don't need exact values always such as speed, temperature, pressure and current.Analogue...
