Difference between Analog Computer and Digital Computer
1. Analog Computer :
1. Analog Computer : Analog computer system is the very old computer system which operates on the mathematical variables in the form of continuously changeable physical quantities/entities like mechanical, electrical, hydraulic, etc. They use continuous values rather than discrete values so they work on analog signal. At the time of at the time of the 1950s–1960s these analog computers were first used. Analog computers are limited in accepting the problems and also they can never be extremely accurate.
2. Digital Computer :
2. Digital Computer :Digital computers are the computer systems/machines which uses the binary number system, which has two digits: 0 and 1 and performs many computational tasks. It processes the data represented in discrete and the main three components of digital computers are input, processing and output. The first digital computer was designed for numerical computations in the late 1940s. Digital computers give results with more accuracy as it is not dependent upon physical quantities for processing a task.

Answer:
Explanation:
01. Analog computers works with continuous values or these types of systems process continuous data.
Digital computers works with discrete values or these types of systems process discrete data.
02. Speed of analog computers is less than the digital computers.
Speed of digital computers is more than the analog computers.
03. Analog computer has very low or limited memory and it can store less amount of data.
Digital computer has very big memory it can store large amount of data.
04. Analog computer has no state.
Digital computer has On and Off these 2 steps.
05. Analog computers are less reliable than digital computers.
Digital computers are more reliable than analog computers.
06. Its performance is comparatively low.
Its performance is very hig
