The World Wide Web (WWW) 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.
Electronic mail consists of messages sent through a computer network
to specific groups or individuals. Here are some default ports for e-mail:
Sending voice signals over the Internet is called Voice over IP or VoIP.
Session Initiated Protocol (SIP) is an internationally recognized
standard for implementing VoIP. SIP is an application-layer control
(signaling) protocol that handles the setting up, altering and tearing
down of voice and multimedia sessions over the Internet.
SIP is transported primarily over UDP but can also be transported over
TCP.
