Types of Computer We 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 Computer Digital Computer Hybrid Computer 1) Analogue Computer Analogue 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 computers directly accept the data from the measuring device without first converting it into numbers and codes. They measure the continuous changes in physical quantity and generally render output as a reading on a dial or scale. Speedometer and mercury thermometer are examples of analogue c...
