RJ-11 - A connector/socket for two pairs (four wires) of twisted pair cable that is used primarily to
connect telephone equipment in the United States.
RJ-45 - A connector/socket for four pairs (either wires) of twisted pair cable that is used commonly
to connect computers onto a local-area network, especially to the Ethernet. A RJ-45 connector
looks similar to the RJ-11 connector used for connecting a telephone equipment, however RJ-45
is slightly wider than RJ-11.
Router - A hardware device that connects two separately functional networks that use same or
different protocols. Routers look at the destination addresses on the packets passing through
them and then decide the best route to send them on.
SDSL - Symmetrical DSL — A DSL technology that provides the same amount of bandwidth (up to
1.5 Megabits) both upstream and downstream.
Segment - A physical or logical portion of a network. An Ethernet segment does not cross any bridge

10 Base-T - Wiring standard used for Ethernet networks that can transmit data at up to 10 Mbps
transmission using baseband unshielded twisted pair cable. Maximum allowable cable length is
100 meters (330 feet).
Twisted pair cable - A cable that consists of two wires twisted together. This cable is less
