Digital computer v/s Analog computer

Analog computer don't have ability of digital computer to store data in large quantities,nor do they have the comprehensive logical facilities afforded by programming digital machine.although the arithmetic function perform by the computing unit are more complex in analogue machine than in digital system. Analog machine are design for specific applications but most electrical and electronic analog computer provide a number of different computing devices which can be connected together via plug board or provide different methods of operations for special problem. In digital machine number to be stored to be used in same calculations were represented by physical quantities such as electrical voltage.
