RIP

Routing Information Protocol The original TCP/IP routing protocol.

There are two versions of RIP: version and version II.

RJ-11

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.

RJ-45

Registered Jack Standard-45 The 8-pin plug used in transmitting

data over phone lines. Ethernet cabling usually uses this type of

connector.

routing

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.

rule

See filtering rule, NAT rule.

SDNS

Secondary Domain Name System (server) A DNS server that can be

used if the primary DSN server is not available. See DNS.

SNMP

Simple Network Management Protocol The TCP/IP protocol used

for network management.

Splitter

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.

splitterless

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.

STUN

Simple Traversal of UDP (User Datagram Protocol) through NAT

(Network Address Translation)

subnet

A subnet is a portion of a network. The subnet is distinguished

from the larger network 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.

Subnet mask

A mask that defines a subnet. See also network mask.

TCP

See TCP/IP.

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 reassembling them at the destination,
