Difference Between Analog Computer & Digital Computer
The analog computer processes work electronically by analogy. It uses an analog for each variable and produces analogs as output. It, thus, measures Continuously. It does not produce number but produces its results in the form of graph. It is more efficient in continuous calculations. Digital computer performs calculations by counting and thus counts discretely. It is the most versatile machine.
The analog computer accepts variable electrical signals (analog values) as inputs, and its output is also in the form of analog electrical signals.
Digital computer operates on inputs which are on-off type (being digits 0 or 1) and its output is also in form of on-off signal. Analog computer operates by measuring analog signals whereas digital computer are based on counting operation.
Most of the computers available today are digital computers and therefore term computer usually stands for digital computers.
