A computer is a programmable machine that receives input, stores and automatically manipulates data, and provides output in a useful format.
Although mechanical examples of computers have existed through much of recorded human history, the first electronic computers were developed in the mid-20th century (1940 - 1945). These were the size of a large room, consuming as much power as several hundred modern personal computers (PCs). Modern computers based on
integrated circuits are millions to billions of times more capable than the early
machines, and occupy a fraction of the space.
