DESCRIPTION

possible by e-mail.
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.
BitTorrent is a free P2P (peer-to-peer) sharing tool allowing you to distribute large software
and media files. BitTorrent requires you to search for a file with a searching engine yourself.
It distributes files by corporation and trading, that is, the client downloads the file in small
pieces and share the pieces with other peers to get other half of the file.
