Terminator
A resistor connected to the end of a coax cable which is
intended to match the characteristic impedance of a
cable. Signals are dissipated in the terminator,
eliminating reflections.
Topology
Topology is the organization of network components.
The topology of Token Ring network components is a
ring.
Uptime
The amount of uninterrupted time that a resource (such
as a print server) has been available.
Transceiver
In Ethernet networks, a transceiver is used to couple
electrical signals to and from an adapter to the
transmission media. In ThinLAN and 10BASE-T
networks, the transceiver is integrated directly onto the
network adapter card.
Twisted Pair
A pair of wires that are twisted together to minimize
crosstalk. Crosstalk is minimized with twisted pair
wiring by canceling the magnetic fields generated in each
of the twisted wires. Twisted pair cable (UTP or STP) is
typically made up of several twisted pairs of wires.
UTP (Unshielded Twisted Pair)
Cable that is twisted by pairs but not shielded. This
minimizes crosstalk by canceling the magnetic fields
generated in each of the twisted wires, but only when a
single twisted pair is used for Transmit or Receive.
