The Web is called the Web because all the Web pages are connected to other pages. From a Web page on car repair, for example, you might be able to go directly to the home pages of car manufacturers, parts suppliers, car magazines, and so on. To use the World Wide Web, you need a piece of software called a Web browser. All you need is the other person's email address. Email is popular because it is fast and messages cost nothing.
Messages can travel anywhere in the world in minutes - at most, a few hours.
Email messages can also have attachments - separate files that travel along with the message. This is an easy way to send a copy of a word-processing document, graphic file, or spreadsheet to someone far away. Usenet News Usenet is a collection of Internet-wide discussion groups, or newsgroups. Over 10,000 newsgroups exist, each dedicated to the discussion of one specific topic. You use news client software to post messages to a particular newsgroup, and to read the messages that others have posted to that group.
