Conventionally, a modern computer consists of at least one processing element, typically a central processing unit (CPU), and some form of memory.

It was discovered in 1901 in the Antikythera wreck off the Greek island of Antikythera, between Kythera and Crete, and has been dated to circa 100 BC.A computer is a device that can be instructed to carry out arbitrary sequences of arithmetic or logical operations automatically.The ability of computers to follow generalized sets of operations, called programs, enables them to perform an extremely wide range of tasks.Such computers are used as control systems for a very wide variety of industrial and consumer devices.This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer assisted design, but also in general purpose devices like personal computers and mobile devices such as smartphones.As slide rule development progressed, added scales provided reciprocals, squares and square roots, cubes and cube roots, as well as transcendental functions such as logarithms and exponentials, circular and hyperbolic trigonometry and other functions.

Slide rules with special scales are still used for quick performance of routine calculations, such as the E6B circular slide rule used for time and distance calculations on light aircraft.1945 under this name; [in a] theoretical [sense] from 1937, as Turing machine".Devices have been used to aid computation for thousands of years, mostly using one-to-one correspondence with fingers.A combination of the planisphere and dioptra, the astrolabe was effectively an analog computer capable of working out several different kinds of problems in spherical astronomy.An astrolabe incorporating a mechanical calendar computer circa 1000 AD.The first digital electronic calculating machines were developed during World War II.
