The World Wide Web is an Internet system to distribute graphical, hyper-linked 

information, based on Hyper Text Transfer Protocol (HTTP) - a client/server 

protocol for the World Wide Web. The Web is not synonymous with the 

Internet; rather, it is just one service on the Internet. Other services on the 

Internet include Internet Relay Chat and Newsgroups. The Web is accessed 

through use of a browser.
•

User-defined services are user specific services configured using known ports 

and applications.
