A computer is any device capable of making calculations--it performs a computation and produces an answer. But this is a little too broad to describe most computers today. Today's computers can perform very complex calculations at extremely high speeds.

The computers most people think of, their desktop computers, their laptops or notebook computers are 'general purpose' machines. All general purpose computers have a place to store instructions (a program), registers to store intermediate values created during computation and a computation engine to perform logical or mathematical calculations. Increasingly, computers are being integrated with everything you can think of, from your car, to your audio system, your appliances, your phone, virtually everything has a computer inside it these days.

Modern computers are a combination of firmware, hardware and software. This tutorial will focus on the main components in every computer, the different kinds of computer hardware, computer software and computer firmware.
