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.
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
A TCP/IP protocol used for network management, often
performed from a remote site.
SNTP Simple Network Time Protocol
An Internet protocol that specifies how a network can
synchronize its time with a clock on the Internet.
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.
supplicant In the 802.1x protocol, a device that attempts to log on to a
network by providing authentication information, which is
compared to information stored on an authentication server.
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 responsible 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 refers 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 files from a remote computer, Telnet
allows you to log into and use a computer from a remote
location.
TFTP Trivial File Transfer Protocol
A protocol for file transfers, TFTP is easier to use than File
Transfer Protocol (FTP) but not as capable or secure.
TTL Time To Live
A field in an IP packet that limits the life span of that packet.
Originally meant as a time duration, the TTL is usually
represented instead as a maximum hop count; each router that
