Route table A table listing information about routes to other hosts or networks, such as
the remote network or host address, the interface down which the route exists, the
distance to the remote address and the cost of sending data over the route.
Router A system responsible for making decisions about which of several paths network
(or Internet) traffic will follow. To do this it uses a routing protocol to gain information
about the network, and algorithms to choose the best route based on several criteria
known as “routing metrics”.
S
Server A network device that provides services to client stations. Examples include file
servers and print servers.
Service A term used with the router to refer to a connection to another port on (another)
router, used to access dialup modems, hosts that do not support TCP/IP and other
asynchronous devices.
SNMP Simple Network Management Protocol. The Internet standard protocol developed
to manage nodes on an IP network. See MIB.
Subnet A portion of a network, which may be a physically independent network segment,
which shares a network address with other portions of the network and is distinguished
by a subnet number. A subnet is to a network what a network is to an internet.
Subnet Address The subnet portion of an IP address. In a subnetted network, the host
portion of an IP address is split into a subnet portion and a host portion using an address
or subnet mask. See subnet mask, IP address and network address.
Subnet Mask A bit mask used to select bits from an Internet address for subnet
addressing. The mask is 32 bits long and selects the network portion of the Internet
address and one or more bits of the local portion. Sometimes called address mask.
T
TCP Transmission Control Protocol. The TCP/IP standard transport layer protocol in the
Internet suite of protocols, providing reliable, connection-oriented, full-duplex streams. It
uses IP for delivery.
TCP/IP Protocol Suite Transmission Control Protocol over Internet Protocol. This is
common shorthand, which refers to the suite of transport and application protocols that
runs over IP. See IP, ICMP, TCP, UDP, FTP, Telnet, and SNMP.
Telnet The virtual terminal protocol in the TCP/IP suite of protocols, which allows users
of one host t o log into a remote host and interact as normal terminal users of that host.
