Content vs. transport. Many people use the terms Web and Internet synonymously. In casual conversation such as "I was on the Internet" or "I was on the Web," there is no difference. However, in fact, the Web is just one of the services deployed on the Internet. Just as cargo is transported by a truck on a highway, a Web page is transported by packets on the Internet. When information is sent over the Internet, it is broken apart and packaged inside Internet Protocol packets or "IP packets." See packet switching and TCP/IP.

Not Just Web Pages
Every form of information travels over the Internet, including e-mail messages, newsgroup news, instant messages as well as audio, video and data files of all description. Countless client-to-server and client-to-client (peer-to-peer) applications have been and will continue to be developed using the Internet as transport between sending and receiving stations. See World Wide Web, Internet and IP.
