A computer is a machine that can be programmed to perform sequences of arithmetic or logical operations automatically. Modern computers can perform general sets of operations known as programs. These programs enable the computer to perform a variety of tasks. A computer system is a “complete” computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for “complete” operation. The term can also refer to a group of computers that are linked together and function together, such as a computer network or computer cluster.
A wide range of industrial and consumer products use computers as control systems. Simple special-purpose devices such as microwave ovens and remote controls are included, such as industrial robots and factory equipment such as computer-aided designs, as well as general-purpose equipment such as personal computers and mobile devices such as smartphones. Computers power the Internet, which connects millions of other computers and users.
Early computers were used only for calculations. Simple hand-operated instruments such as the abacus have helped people calculate since ancient times. At the beginning of the Industrial Revolution, some mechanical devices were made to automate long tedious tasks, such as guiding patterns for looms. More sophisticated electrical machines performed specialized analog calculations in the early 20th century. The first digital electronic counting machine was developed during World War II. The first semiconductor transistors in the late 1940s were followed by silicon-based MOSFET (MOS transistors) and monolithic integrated circuit (IC) chip technology in the late 1950s, leading to the microprocessor and microcomputer revolution in the 1970s . The speed, power, and versatility of computers have increased dramatically since then, with the number of transistors increasing at a rapid rate (as predicted by Moore’s Law), leading to the transition from the late 20th century to the 21st century. The digital revolution took place in the beginning.
Traditionally, a modern computer has at least one processing element, usually a central processing unit (CPU) in the form of a microprocessor, along with some type of computer memory, usually semiconductor memory chips. The processing element performs arithmetic and logical operations, and an indexing and control unit can change the order of operations in response to the stored information. Peripheral devices include input devices (keyboards, mice, joysticks, etc.), output devices (monitor screens, printers, etc.), and input/output devices that perform both functions (eg, touchscreens of the 2000s). Peripheral devices allow information to be received from an external source and they enable the result of operations to be saved and retrieved.
