URL
A URL is a Uniform Resource Locator. Think of it as a networked extension of the standard filename concept: not only can you point to a file in a directory, but that file and that directory can exist on any machine on the network, can be served via any of several different methods, and might not even be something as simple as a file: URLs can also point to queries, documents stored deep within databases, the results of a finger or archie command, or whatever. Here is an example of a URL it’s the address of the web site where I found out about URL''s: http://www.ncsa.uiuc.edu/demoweb/url-primer.html

HTTP
Hyper Text Transfer Protocol

COOKIES
A small set of files used to help when you go on the Internet (they are like a footprint that you leave behind, and next time you go to that site, they know you are visiting again)

BAUD RATE
Is the speed of the modem, Bytes per second (that’s the amount of information that can be transferred from one computer to another in a selected amount of time) Our modem is a 56K modem, that means it can transfer 56000 characters per second.

WWW
World wide web.

COMP
Shortened word for computer.

The whole of the Internet is made up of lots of different categories and sections such as:
Games
Chat rooms
Shopping
Jokes
Information
And lots more that I have not mentioned.The Internet is a world wide collection of information which is stored on lots of different computers in many different buildings.
The World Wide Web goes on so people can find out about different things without having to leave their own homes.
The INTERNET began because the United States Military wanted a way of protecting their computer information and it was important that if a computer site was destroyed by the enemy, then other computers would still work. In the 1970''s and 1980''s the Internet was mainly used by Military and University people, however, from the 1990''s it became accessible by many people at home and at work.
Today, many people use the Internet to send mail, to research information, to do banking, to do shopping, and to chat with friends.When you go surfing on the net, you will find pages which are made up of lots of links, the links will take you to more information about this topic, or might take you to a totally different site.An example of a hyperlink are the buttons to go home on this page, click on the HOME button and you will jump to the top of the document.

What do you need to connect to the Internet?

• Computer
• Modem
• Telephone Line
• Internet Software
• Time with an Internet Service Provider (ISP)

When you join an ISP, (e.g. Dingo Blue, Bigpond etc) you are given a username and password and a telephone number to dial on your computer. When you log onto your ISP, you can then search the internet - surfing - you will use a search engine like yahoo. You can also send and receive mail, I use Hotmail, this lets me check my emails from any computer that is logged onto the internet. I can talk to my friends using MSN Messager. I have also used MICQ to chat with lots of people throughout the world.
Sometimes, you might want to shop for presents on the Internet, for instance, you can search using YAHOO for what you want and lots of sites will be displayed, you can then go into the site, and add the items that you want to buy into your shopping cart. You usually need a credit card to shop over the internet. You can also win prizes over the internet. For example, I was able to collect tokens by buying boxes of Arnotts biscuits, then when I had enough tokens, I was able to post them to the competition and they posted me a password to log onto the prize site, I then selected the CD I wanted and typed in my password, a couple of weeks later, my CD arrived in the mail. You can also find really cool screen savers and pictures on the net. You can download music from sites like NAPSTER, you just type in the song that you want and you download it, it takes a little while to download the song, but then you can play them whenever you want.

Advantages and Disadvantages of the INTERNET
Advantages Disadvantages
More ways to communicate You can get bugs (viruses) on your computer
You don''t have to leave your house to shop More local businesses may have to close down because people are buying their products over the net
Napster - you don''t have to buy CD''s to listen to your favourite music NAPSTER - sometimes they don''t have all the songs you want. Music companies are losing money, there was a court case recently over copyright of songs.
You can talk with people all over the world using chat sessions Chatting - you don''t know who you are talking to and if they are telling the truth or not
