WLAN Router
RIP
Routing Information Protocol
The original TCP/IP routing protocol. There are two versions of RIP: version I and
version II.
RJ-11
Registered Jack Standard-11
The standard plug used to connect telephones, fax machines, modems, etc. to a te-
lephone port. 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 ecient ro-
ute, based on the data’s destination IP address and current network conditions. A
device that performs routing is called a router.
SDNS
Secondary Domain Name System (server)
A DNS server that can be used if the primary DSN server is not available. See DNS.
subnet
A subnet is a portion of a network. The subnet is distinguished from the larger ne-
twork by a subnet mask that 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 ne-
twork. See network mask.
subnet mask
A mask that denes a subnet. See 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, while IP is re-
sponsible for delivering the packets from source to destination. When TCP and IP
are bundled with higher-level applications such as HTTP, FTP, Telnet, etc., TCP/IP re-
fers to this whole suite of protocols.
Telnet
An interactive, character-based program used to access a remote computer. While
HTTP (the web protocol) and FTP only allow you to download les from a remote
computer, Telnet allows you to log into and use a computer from a remote location.
