ANALOG COMPUTER Meaning and
Definition
-
An analog computer is a device that performs computations and represents data using continuous physical quantities, such as electrical voltages or mechanical analogs. Unlike digital computers, which manipulate discrete values represented in binary form, analog computers work on the principle of measuring, simulating, or approximating physical quantities, allowing for a more direct and continuous representation of real-world phenomena.
Analog computers use physical components, such as resistors, capacitors, and operational amplifiers, to model and solve mathematical equations. These equations are typically written as differential equations, integral equations, or other forms of mathematical models. By manipulating the parameters of the physical components, analog computers can solve problems across various fields, including physics, engineering, and biology.
The output of an analog computer is obtained through the physical interactions of the components, resulting in continuous signals that directly represent the solution to the problem being solved. These signals can be displayed visually on oscilloscopes or other graphing devices, allowing users to directly observe the behavior of the system being modeled.
Although they have been largely replaced by digital computers due to limitations in accuracy, precision, and complexity, analog computers remain useful in certain niche applications. Their ability to simulate continuous systems in real-time makes them applicable in areas such as control systems, signal processing, and certain scientific research fields where the behavior of physical systems can be effectively modeled using continuous variables.

Etymology of ANALOG COMPUTER
The word "analog" in "analog computer" is derived from the Greek word "analogos", meaning proportionate or comparable. "Analogos" is a combination of "ana" meaning "according to" and "logos" meaning "proportion". Therefore, an "analog computer" is named so because it operates in a manner that is proportionate or similar to the behavior of a physical system it models.
