Subnet Mask

A subnet mask, which may be a part of the TCP/IP information provided by your ISP, is a set of four

numbers (e.g. 255.255.255.0) configured like an IP address. It is used to create IP address numbers

used only within a particular network (as opposed to valid IP address numbers recognized by the

Internet, which must be assigned by InterNIC).

TCP/IP, UDP

Transmission Control Protocol/Internet Protocol (TCP/IP) and Unreliable Datagram Protocol (UDP).

TCP/IP is the standard protocol for data transmission over the Internet. Both TCP and UDP are

transport layer protocol. TCP performs proper error detection and error recovery, and thus is reliable.

UDP on the other hand is not reliable. They both run on top of the IP (Internet Protocol), a network

layer protocol.

TELNET

It is the virtual terminal protocol in the Internet suite of protocols. Allows users of one host to log into a

remote host and act as normal terminal users of that host.

VCI

Virtual Circuit Identifier is part of the ATM cell header. A VCI is a tag indicating the channel over which

a cell will travel. The VCI of a cell can be changed as it moves between switches via Signaling.

VPI

Virtual Path Identifier is part of the ATM cell header. A VPI is a pipe for a number of Virtual Circuits.

WAN

Wide Area Network is a network that connects computers located in geographically separate areas

(e.g. different buildings, cities, countries). The Internet is a wide area network.

Web-based management Graphical User Interface (GUI)

Many devices support a graphical user interface that is based on the web browser. This means the

user can use the familiar Netscape or Microsoft Internet Explorer to Control/configure or monitor the

device being managed.
