A set of rules governing the transmission of data. In order for a data transmission
to work, both ends of the connection have to follow the rules of the protocol.
In a physically separate location. For example, an employee away on travel who
logs in to the company's intranet is a remote user.
Routing Information Protocol The original TCP/IP routing protocol. There are two
versions of RIP: version and version II.
Registered Jack Standard-11 The standard plug used to connect telephones,
fax machines, modems, etc. to a telephone jack. It is a 6-pin connector usually
containing four wires.
Registered Jack Standard-45 The 8-pin plug used in transmitting data over phone
lines. Ethernet cabling usually uses this type of connector.
Forwarding data between your network and the Internet on the most efficient
route, based on the data's destination IP address and current network conditions. A
device that performs routing is called a router.
See filtering rule, NAT rule.
Secondary Domain Name System (server) A DNS server that can be used if the
primary DSN server is not available. See DNS.
Simple Network Management Protocol The TCP/IP protocol used for network
management.
A device that splits off the voice component of the DSL signal to a separate line, so
that data and telephone service each have their own wiring and jacks. The splitter
is installed by your telephone company where the DSL line enters your home. The
CO also contains splitters that separate the voice and data signals, sending voice
to the PSTN and data on high-speed lines to the Internet. See also CO, PSTN,
splitterless, microfilter.
A type of DSL installation where no splitter is installed, saving the cost of a service
call by the telephone company. Instead, each jack in the home carries both voice
and data, requiring a microfilter for each telephone to prevent interference from the
data signal. ADSL is usually splitterless; if you are unsure if your installation has a
splitter, ask your DSL provider. See also splitter, microfilter.
A subnet is a portion of a network. The subnet is distinguished from the larger net-
work by a subnet mask which selects some of the computers of the network and
excludes all others. The subnet's computers remain physically connected to the
rest of the parent network, but they are treated as though they were on a separate
network. See also network mask.
A mask that defines a subnet. See also network mask.
See TCP/IP.
Transmission Control Protocol/Internet Protocol The basic protocols used on the
Internet. TCP is responsible for dividing data up into packets for delivery and reas-
sembling them at the destination, while IP is responsible for delivering the packets
from source to destination. When TCP and IP are bundled with higher-level applica-
tions such as HTTP, FTP, Telnet, etc., TCP/IP refers to this whole suite of protocols.
An interactive, character-based program used to access a remote computer. While
HTTP (the web protocol) and FTP only allow you to download files from a remote
computer, Telnet allows you to log into and use a computer from a remote location.
