ANALOGUE COMPUTERS Meaning and
Definition
-
Analogue computers refer to a type of computing device that operates on continuous data and uses physical quantities to represent and manipulate information. Unlike digital computers that utilize discrete values and binary systems, analogue computers process data in a continuous form, representing quantities such as voltage, current, or pressure.
An analogue computer consists of various interconnected components, including electronic circuits, amplifiers, potentiometers, and integrators, among others. It typically employs analog models or simulations to solve mathematical equations or perform experiments in various fields such as engineering, physics, and scientific research.
These computers are renowned for their precise calculations, speed, and ability to concurrently process multiple equations. They excel at solving complex differential equations and real-time simulations that require continuous and real-world input/output relationships. Analogue computers have been widely used in applications like weather prediction, fluid dynamics, control systems, and electronic circuit design.
The output of an analogue computer is represented by physical variables, often in the form of voltage, position, or rotation. These outputs can be displayed on oscilloscopes or recorded with chart recorders, enabling users to interpret results graphically.
While digital computers have largely superseded analogue computers due to their flexibility and wider range of applications, analogue computers still find niche uses in specific areas where their precision, physical models, and real-time computation capabilities offer distinct advantages.

Etymology of ANALOGUE COMPUTERS
The word "analogue" originated from the Greek word "analogos", which means "proportionate" or "corresponding". It entered the English language in the late 19th century, and its usage in relation to computing developed much later.
The term "analogue computers" emerged in the mid-20th century as a way to describe computational devices that operate based on continuous physical variables. These computers use mechanisms such as gears, levers, and rotating shafts to represent and manipulate data. The etymology of the word "computer" can also be traced to Latin, where "computare" means "to calculate".
The word "analogue" was chosen to distinguish these computers from their digital counterparts, which represent data using discrete states or digits. "Analogue computers" were initially used in various scientific and engineering fields, performing tasks like solving complex differential equations, running simulations, and analyzing data.
