Users Manual

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.

Transport

Transport refers to the physical method by which data is transmitted (e.g., Ethernet, Token Ring, etc.). Different physical network hardware and cable layout are required for different transports.

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.

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.

VoIP (Voice over Internet Protocol)

The technology used to transmit voice conversations over a data network using the Internet Protocol.

Twisted Pair

A pair of wires that is 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.
