//Did you know that the word Internet is always capitalized in English?// || The Internet is not synonymous with the **World Wide Web**. Browsing the World Wide Web is only one of several different components which make up the Internet. The main components of the Internet are: The World Wide Web (WWW), also just called the Web, came into existence in 1980 when Tim Berners-Lee, a consultant for CERN in Europe, wrote a program that allowed special links between arbitrary computers on the Internet. With the new program, data could be transmitted and received over the Internet in the form of text, graphics, and sound from locations called sites. The Web has now grown to include millions of Internet sites.
 * What is the Internet?**
 * The **Internet** is a global network made up of millions of interconnected computers. What makes the Internet so incredibly powerful is that these millions of computers store an extraordinary amount of information which is accessible from any computer connected to the Internet. This information is different from that stored in books in two ways. First, all of the information is stored, transmitted, and received digitally which means that it can be accessed in a number of different forms including text, video, and audio. Second, the Internet is interactive which means that the information you receive is a result of the selections you make. For example, in contacting a news source you could be asked to select the type of news you are interested in sports, financial, political, movie reviews, etc. After making a selection you would then be shown a list of stories within that category. Selecting a specific title might then display a review in text and show a short clip from the movie using video and audio. ||

Short for electronic mail, the transmission of messages over communications networks. The messages can be notes entered from the keyboard or electronic files stored on disk. Most mainframes, minicomputers, and computer networks have an e-mail system. Some electronic-mail systems are confined to a single computer system or network, but others have gateways to other computer systems, enabling users to send electronic mail anywhere in the world. Companies that are fully computerized make extensive use of e-mail because it is fast, flexible, and reliable.

Today the **Internet** is a worldwide phenomenon with no geographic borders. It connects people down the street and across the world. It is critical to academic research and to the growing national and global economy. It is said that in Canada, 99% of all school aged children have used or seen the Internet. That is an incredible accomplishment since less than 10 years ago, however, hardly anyone even knew what the Internet was. In fact, the birth of the Internet was probably one of the most profound technological achievements of the 20th century, yet few people know much about its history or how it works. The Internet was born as a result of the American government realizing that it would be cheaper and more efficient for research programs and scientists if one computer could contact, or “talk” to another, so that the user could tap into the computing power of other machines besides his/her own. So a Department of Defense program called the Advanced Research Projects Agency ( **ARPA** ) set out to figure out a way to connect one computer to another. The project was coined “ **ARPAnet** ” since the goal was to create a network of connections among different computers.
