Analog computerAnalog computer
Analog computer measures and answer the questions by the method of “HOW MUCH”. The input data is not a number infect a physical quantity like tem, pressure, speed, velocity.
Signals are continuous of (0 to 10 V)Accuracy 1% ApproximatelyHigh speedOutput is continuousTime is wasted in transmission time

Digital ComputersDigital Computers
Digital computer counts and answer the questions by the method of “HOW Many”. The input data is represented by a number. These are used for the logical and arithmetic operations.
Signals are two level of (0 V or 5 V) Accuracy unlimited low speed sequential as well as parallel
processing Output is continuous but obtain when
computation is completed.
