A 

computer is a machine that can be programmed to carry out sequences of arithmetic or logical


operations automatically. Modern computers can perform generic sets of operations known
as programs. These programs enable computers to perform a wide range of tasks. A computer
system is a "complete" computer that includes the hardware, operating system (main software),
and peripheral equipment needed and used for "full" operation. This term may also refer to a
group of computers that are linked and function together, such as a computer
network or computer cluster.
A broad range of industrial and consumer products use computers as control systems. Simple
special-purpose devices like microwave ovens and remote controls are included, as are factory
devices like industrial robots and computer-aided design, as well as general-purpose devices
like personal computers and mobile devices like smartphones. Computers power the Internet,
which links hundreds of millions of other computers and users.
Early computers were meant to be used only for calculations. Simple manual instruments like
the abacus have aided people in doing calculations since ancient times. Early in the Industrial
Revolution, some mechanical devices were built to automate long tedious tasks, such as guiding
patterns for looms. More sophisticated electrical machines did specialized analog calculations in
the early 20th century. The first digital electronic calculating machines were developed
during World War II. The first semiconductor transistors in the late 1940s were followed by
the silicon-based MOSFET (MOS transistor) and monolithic integrated circuit (IC) chip
technologies in the late 1950s, leading to the microprocessor and the microcomputer revolution in
the 1970s. The speed, power and versatility of computers have been increasing dramatically ever
since then, with transistor counts increasing at a rapid pace (as predicted by Moore's law),
leading to the Digital Revolution during the late 20th to early 21st centuries.
Conventionally, a modern computer consists of at least one processing element, typically
a central processing unit (CPU) in the form of a microprocessor, along with some type
of computer memory, typically semiconductor memory chips. The processing element carries out
arithmetic and logical operations, and a sequencing and control unit can change the order of
operations in response to stored information. Peripheral devices include input devices
(keyboards, mice, joystick, etc.), output devices (monitor screens, printers, etc.), and input/output
devices that perform both functions (e.g., the 2000s-era touchscreen). Peripheral devices allow
information to be retrieved from an external source and they enable the result of operations to be
saved and retrieved.
