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.
