An analog computer uses analog signals that signifies a continuous signal that keeps changes with a time period. An analog computer recognizes the data as a continuous measurement. Its output is usually displayed on a meter or graph. It has low memory and fewer functions. For example, Speedometer, Analog clock etc.
A digital computer uses digital signals that signifies a discrete signal that carries binary data and has discrete values. A digital computer processes data in numerical form using digital circuits. It performs arithmetic and logic operations with discrete values. These values are 0 and 1. For example digital watch, digital scoreboard etc.
