History
A Computer is a machine which manipulates data according to a list of instructions. Computers take numerous physical forms. The first devices that resemble modern computers date to the mid-20th. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers.
Modern computers are based on comparatively tiny ICs and are millions to billions of times more capable while occupying a fraction of the space. Today, simple computers may be made small enough to fit into a wrist watch and be powered from a watch battery.
The ability to store and execute lists of instructions called programs makes computers extremely versatile and distinguishes them from calculators. The Church–Turing thesis is a mathematical statement of this versatility: Any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore, computers with capability and complexity ranging from that of a personal digital assistant to a supercomputer are all able to perform the same computational tasks given enough time and storage capacity.
