computer
A computer is a programmable machine that receives input, stores and manipulates data, and provides output in a useful format.
While a computer can, in theory, be made out of almost anything (see misconceptions section), and 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). Originally, they 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 Simple computers are small enough to fit into mobile devices, and can be powered by a small battery. Personal computers in their various forms are icons of the Information Age and are what most people think of as "computers". However, the embedded computers found in many devices from MP3 players to fighter aircraft and from toys to industrial robots are the most numerous.

Hardware & Software
Hardware can be defined as items that you can actually touch or move from one desk or room to another.
Software can be defined as a set of instructions that tells the computer how to behave.
A special type of software, called the operating system (OS), tells the computer how to use all the different it can be connected to. e.g. printer, disk drive, keyboard,
