DESCRIPTION
File Transfer Program enables fast transfer of files, including large files
that may not be possible by e-mail. FTP uses port number 21.
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.
WWW uses port 80.
Telnet is the login and terminal emulation protocol common on the
Internet and in UNIX environments. It operates over TCP/IP networks.
Its primary function is to allow users to log into remote host systems.
Telnet uses port 23.
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
SMTP - port 25
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, using the default port number 5060.
BitTorrent is a free P2P (peer-to-peer) sharing tool allowing you to
distribute large software and media files using ports 6881 to 6889.
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.
Online gaming services lets you play multiplayer games on the Internet
via broadband technology. One example is Microsoft's Xbox Live, which
uses port 3074. As of this writing, your NBG-417N supports Xbox,
Playstation, Battlenet and MSN Game Zone.
