Computer

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.

What is the Internet?

The Internet is the worldwide super-network of publicly accessible computers. The Internet is composed of thousands of networks all around the world that have agreed to connect and communicate with each other and transfer data between each other. There is no International Law mandating the Internet's existence nor any body solely responsible for governing or policing the Internet. A wide range of Internet tutorials are provided here, covering questions such as "What is the Internet?" and "How does the Internet work?" and the history of the Internet as well as the majority of networking technologies, network protocols and communications protocols used by the Internet, as well as a bit of history of the Internet and some background.

I highly recommended that you read the Theory section of this site, especially the OSI Model, and Binary sections before beginning the Internet tutorials, as they will help you get the most out of these tutorials about the Internet.
