A computer is a machine that manipulates data according to a list of orders.

The first strategy that resemble modern computers date to the mid-20th century, though the computer concept and various equipment similar to computers exist earlier. Early electronic computers were the volume of a large room, consuming as much power as several hundred modern personal computers.Modern computers are based on tiny incorporated circuits and are millions to billions of times more proficient while occupying a part of the space. Today, simple computers may be made small sufficient to fit into a wristwatch and be motorized from a watch battery. Personal computers, in various forms, are icons of the in order Age and are what most people think of as "a computer"; however, the most ordinary form of computer in use today is the embedded computer. Embedded computers are small, simple strategy that are used to control other plans for example, they may be found in machines range from boxer airplane to industrial robots, digital cameras, and children's toys.

The ability to store and carry out lists of commands called programs makes computers enormously resourceful and distinguishes them from calculators. The Church–Turing thesis is a numerical statement of this flexibility: any computer with a certain least amount capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, computers with capability and difficulty ranging from that of a personal digital supporter to a supercomputer are all able to do the same computational tasks given enough time and storage ability.
