possible by e-mail.
WWW 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.
E-Mail Electronic mail consists of messages sent through a computer network to specific groups
or individuals. Here are some default ports for e-mail:
• POP3 - port 110
• IMAP - port 143
• SMTP - port 25
• HTTP - port 80
VoIP (SIP) 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 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.
