Analog computers measures and answers thequestions by the method of “HOW MUCH “.•Signals are continuous of (0 to 10V)•Accuracy 1% approximately•High speed•Output is continuous.•Time is wasted in transmission time
Digital computersDigital computers counts and answers the questions by the method of HOW MANY. The input data is represented by a number. These are used for logical and arithmetic operations. Signals are of two levels (0V or 5v) Accuracy unlimited Low speed sequential as well as parallel processing Output is continuous but obtain when computation is completed
