Plug-in
Small applications that add new functionality to a Web browser. For example, an audio plug-in allows a browser user to listen to audio files on a Web page or in an email message.

POP
(Point of Presence) -- Physical access point to a long distance carrier or Internet service provider network.

POP3
The Internet standard for mail servers.

Port
An interface on a networking device. A number that identifies a particular Internet application.

PPP
(Point to Point Protocol) -- A protocol that allows a computer to use the Internet protocols (TCP/IP) with a standard phone line and a high-speed modem.

PPTP
(Point to Point Tunneling Protocol) - Protocol used to create LAN-to-LAN tunnels between Windows NT servers that have installed the PPTP protocol. PPTP wraps and encrypts IP packets and sends them to a destination server. This provides secure tunneling between sites from within NT, without extra equipment or changes to the network. This protocol is used to provide security for data when accessing a company network remotely, through the Internet.

Protocol
A formal set of rules and conventions that govern how devices on a network exchange information.

Proxy
An entity that caches frequently accessed documents to conserve network bandwidth and reduce network response times for users.

PSTN
(Public Switched Telephone Network) -- The worldwide public telephone systems.

Remote Access
Term used to describe remote user access via a telecommunications system to the company network.

RFC
(Request For Comments) A Document series used as the primary means for communicating information about the Internet.

Router
A special-purpose, network layer device that manages the connection between two or more networks. The device makes decisions about which of several paths the network (or Internet) traffic will follow.

Security Certificate
Information often stored as a text file that is used by the SSL protocol to establish a secure connection. Security Certificates contain information about who it belongs to, who it was issued by, a unique serial number or other unique identification, valid dates, and an encrypted 'fingerprint' that can be used to verify the contents of the certificate. In order for an SSL connection to be created both sides must have a valid Security Certificate.

Server
A computer, or a software package, that provides a specific kind of service to client software running on other computers. The term can refer to a particular piece of software, such as a WWW server, or to the machine on which the software is running. A single server machine could have several different server software packages running on it, thus providing many different servers to clients on the network.

SLIP
(Serial Line Internet Protocol) -- A protocol that allows a computer to use the Internet protocols (TCP/IP) with a standard phone line and a high-speed modem.

SMDS
(Switched Multimegabit Data Service) -- A high-speed, fiber-based LAN interconnection service that allows users to use a public network service to allocate wide area bandwidth as it is needed.

SMTP
(Simple Mail Transport Protocol) -- The Internet standard protocol for transferring electronic mail messages from one computer to another. SMTP specifies how two mail systems interface and the format of control messages they exchange to transfer mail.

SNMP
(Simple Network Management Protocol) --A network management protocol for the exchange of information among network components. Network management applications use this information to provide network managers with views into network traffic for device configuration, troubleshooting, and network planning.

Spam
The sending of unsolicited email to a large number of people.

SQL
(Structured Query Language) A standard language for querying relational and other databases.

SSL
(Secure Sockets Layer) -- The encrypted security protocol implemented by Netscape in its browsers and servers to provide secure transactions over the Web.

TCP-IP
(Transmission Control Protocol/Internet Protocol) -- A suite of protocols that performs the transfer of data across internetworks, including the Internet.

Telnet
The command and program used to login from one Internet site to another.

Terabyte
1000 [or 1024] gigabytes.

Thread
A chain of articles or messages posted in response to an originating article or message.

Token Ring
Local area network architecture that connects stations in a closed loop and grants permission to send by circulating a token.

UNIX
A multi-user operating system developed by AT&T Bell Labs and currently popular as an application server operating system.

URL
(Universal Resource Locator) -- Uniquely identifies a file available on the World Wide Web.

USENET
A worldwide system of discussion groups, with comments passed among hundreds of thousands of machines.

UUENCODE
(UNIX to UNIX Encoding) -- A program that encodes binary information, such as graphic images or document files, so that they can be sent across the Internet via e-mail.

Veronica
(Very Easy Rodent Oriented Net-wide Index to Computerized Archives) -- Developed at the University of Nevada, Veronica is a constantly updated database of the names of almost every menu item on thousands of gopher servers. The Veronica database can be searched from most major gopher menus.

Virus
Code written to infect computers with destructive macros or applications.

VPN
(Virtual Private Network) -- Provides a mechanism for forwarding dial-up data packets over the Internet in such a way that end users appear as if connected directly to their destination or home network. This is done using a technique called tunneling. Tunnels represent virtual, dedicated connections between the dial-up access point and a destination point somewhere on the network. The destination is usually the point at which a corporation or an enterprise is connected to the Internet.

VRML
(Virtual Reality Modeling Language) A way to specify a 3D scene for viewing over the World Wide Web.

WAIS
(Wide Area Information Servers) -- Sophisticated indexing and search tool for full-text databases.

WAN
(Wide Area Network) -- Computer network serving a wide geographic area.

Web Page
Web sites are collections of electronic 'pages'. Each Web page is an HTML (HyperText Markup Language) document that may contain text, images, or media objects.

WWW
(World Wide Web) -- A collection of Internet host systems that provide information on the Internet, usually in the form of hypermedia.

E-mail
(Electronic Mail) -- Messages, usually text, sent from one person to another via a computer network.

L2TP
(Layer 2 Tunneling Protocol) -- An IEEE standard for tunneling that includes the ability to terminate tunnels at either the NSP or enterprise network, to apply access policies at the firewall, and to perform tunnel switching.

T1-E1
Digital wide area communications circuit provided by telephone carriers for voice and data transmission (1.544 Mbps in U.S.; 2.054 Mbps in Europe); may be divided in 24 separate 64 Kb channels.

T3-E3
Digital wide area communications circuit standard (44.736 Mbps in the U.S.; 34.368 Mbps in Europe).
