UTP AND THIN ETHERNET REPEATERS
Crosstalk —The electrical interference between signals transmitted on
adjacent wires.
Coaxial Cable —This cable consists of an inner core of wiring that conducts
electrical signals, surrounded by an outer conductor that is the return
path. An outer covering protects the wiring.
10BASE2 Ethernet systems use
50-ohm RG58A/U coaxial cable.
Concentrator —Some LAN implementations use concentrators, or access
units, that allow network devices to be interconnected through a central
point. Attaching devices through a central concentrator typically simplifies
the maintenance of the LAN. When connecting a 10BASE-T twisted-pair
network, refer to the concentrator manual for specific cabling guidelines.
Ethernet —A local are a network (LAN) specification that uses baseband
signaling at 10 Mbps, provides multiple access to the transmission medium,
and requires that a transceiver be able to detect the presence of another
transceiver (or collision detection). These three requirements are
abbreviated as Carrier Sense Multiple Access with Collision Detection
(CSMA/CD).
Gateway —A device or program that connects two LANs that use different
protocols and translates between these protocols, allowing devices on the
two networks to communicate with each other.
Hub —A device that extends the maximum physical length of a network by
receiving and then retransmitting signals among network segments. A hub
provides the central connecting point in a star network topology.
IEEE —Institute of Electrical and Electronics Engineers. Members of the
IEEE are drawn from the industry and work together to establish industry
standards. The IEEE 802 committee has issued many definitive documents
on local area network standards.
Internet —Two or more networks that have similar or dissimilar protocols,
connected by gateways or routers.
Interoperability —The ability to exchange information in a network that
contains computers and additional devices that have dissimilar operating
systems or protocols.
Jabber —When a particular interconnection on a line will not stop
transmitting.
Jumper —An electrical conductor that connects two points in a circuit
board is called a jumper. Jumpers are used to select different options
