The World Wide Web may well rank with the seven wonders of the world. Once you spend time on the Web, you will begin to feel like there is no limit to the amount of information you can find. You'll spend hours entertained by the sheer variety of things people post on their websites. Think of it as a system of electronic information linked together across the globe. The Web allows us to communicate in a rich way, by displaying text, full color graphics, photos, sounds and even video.
Web pages are actually electronic files stored on computers located all over the world.
The Internet is known as a client-server system. Your computer is the client, and the remote computer which stores the data is the server. When you're looking at the Louvre's website, your computer has requested the web page from a server located in Paris. The Louvre's server sends the data you've requested over the Internet to your computer. Your web browser interprets the data and displays it on your computer screen.
