A network layer function that determines the path for transmitting packets through a network from source to destination.
Router
A device that supports network communications. A router can connect identical network types, However—unless a
gateway is available—a common protocol, such as TCP/IP, must be used over both networks. Routers may be equipped
to provide WAN line support to the LAN devices they serve. They may also provide various management and
monitoring functions as well as a variety of configuration capabilities.
Routing table
A list of networks maintained by each router on an internet. Information in the routing table helps the router determine
the next router to forward packets to.
Serial port
A connector on the back of the workstation through which data flows to and from a serial device.
Server
A device or system that has been specifically configured to provide a service, usually to a group of clients.
Subnet
A network address created by using a subnet mask to specify that a number of bits in an internet address will be used as a
subnet number rather than a host address.
Subnet Address
An extension of the Internet 32-bit addressing scheme which allows the separation of physical or logical networks within
the single network number. assigned to an organisation. TCP/IP entities outside this organisation have no knowledge of
the internal ‘subnetting’.
Subnet mask
A 32-bit number to specify which part of an internet address is the network number, and which part is the host address.
When written in binary notation, each bit written as 1 corresponds to 1 bit of network address information. One subnet
mask applies to all IP devices on an individual IP network.
RS-232
EIA standard specifying the physical layer interface used to connect a device to communications media.
SNMP
Simple Network Management Protocol - A widely implemented Internet network management protocol that allows
status monitoring, getting/setting of parameters for configuration and control of network devices, such as routers and
bridges.
TCP/IP
Transmission Control Protocol/Internet Protocol - An open network standard that defines how devices from different
manufacturers communicate with each other over one or more interconnected networks. TCP/IP protocols are the
foundation of the Internet, a world-wide network of networks connecting businesses, governments, researchers, and
educators. TCP provides a connection-oriented transport layer ensuring end-to-end reliability in data transmission. IP
provides for network layer connectivity using connectionless datagrams.
TFTP
Trivial File Transfer Protocol - A protocol used to transfer files between IP nodes. TFTP is often used to transfer
firmware and configuration information from a UNIX computer acting as a TFTP server to an IP networking device.
TELNET
Internet standard protocol for remote terminal emulation that allows a user to remotely log in to another device and
appear as if directly connected.
Transparent Bridging
Bridging technique used in Ethernet networks which allows transfer of frames across intermediate nodes using tables
associating end nodes with bridging addresses. Bridges are unknown to the end nodes.
VCI
Virtual Channel Identifier - Number that identifies a channel within a virtual path in a ADSL/ATM environment.
Virtual Channel
