Computers have become an integral part of our lives. They help us perform complex calculations, store vast amounts of data, and communicate with people across the globe. However, not all computers are digital. There exists a type of computer that uses physical quantities to perform calculations, and it is known as the analog computer.
Definitions
An analog computer is a type of computer that uses physical quantities, such as voltage, current, and resistance, to perform calculations. Unlike digital computers, which operate on discrete values, analog computers operate on continuous values. This means that analog computers can handle complex calculations that would be difficult or impossible for digital computers.
Origin
The first analog computers were developed in the early 20th century. They were used primarily for scientific and engineering applications, such as solving differential equations and modeling physical systems. Analog computers were widely used during World War II for tasks such as calculating ballistics trajectories and designing radar systems.
Meaning in different dictionaries
According to the Oxford English Dictionary, an analog computer is “a type of computer that uses physical quantities to perform calculations, as opposed to digital computers that use discrete values.” Merriam-Webster defines an analog computer as “a computer that operates with numbers represented by directly measurable quantities (such as voltage or rotation).”
Associations
Analog computers are often associated with scientific and engineering applications, such as modeling physical systems and solving differential equations. They are also associated with early computing technology, as they were developed before digital computers became widespread.
Synonyms
Synonyms for analog computer include analog calculator, analog machine, and analog simulator.
Antonyms
Antonyms for analog computer include digital computer, electronic computer, and binary computer.
The same root words
The root word of analog computer is “analog,” which comes from the Greek word “analogos,” meaning “proportionate.” The word “computer” comes from the Latin word “computare,” meaning “to calculate.”
