Token
- A special packet that contains data and acts as a messenger or carrier between each
computer and device on a ring topology. Each computer must wait for the messenger to stop at its
node before it can send data over the network.
Token Ring
- A network protocol developed by IBM in which computers access the network through
token-passing. Usually uses a star-wired ring topology.
Topology
- There are two types of topology: physical and logical. The physical topology of a network
refers to the configuration of cables, computers, and other peripherals. Logical topology is the method
used to pass the information between workstations. Issues involving logical topologies are discussed
on the Protocol chapter
Transceiver
(Transmitter/Receiver) - A Device that receives and sends signals over a medium. In
networks, it is generally used to allow for the connection between two different types of cable
connectors, such as AUI and RJ-45.
Tree Topology
- LAN topology similar to linear bus topology, except that tree networks can contain
branches with multiple nodes.
Twisted Pair
- Network cabling that consists of four pairs of wires that are manufactured with the
wires twisted to certain specifications. Available in shielded and unshielded versions.
U
USB (Universal Serial Bus) Port
- A hardware interface for low-speed peripherals such as the
keyboard, mouse, joystick, scanner, printer, and telephony devices.
W
WAN
(Wide Area Network) - A network connecting computers within very large areas, such as states,
countries, and the world.
Workgroup
- A collection of workstations and servers on a LAN that are designated to communicate
and exchange data with one another.
