A communication method where both ends can transmit and receive
simultaneously.
A communication method where one end transmits while the other
end receives, then reverses the process.
A device for local area networks (LANs) that is used to interconnect
multiple devices over an internal bus.
Aka. phase jitter, caused by power line harmonics and perceived in
the form of minor phase changes.
Aka. Multipoint Line, a data link supporting multiple DTE connections,
usually with one DTE controlling the link by polling the other DTEs for
input and addressing output to the other DTEs. Utilizing frequency
division or statistical MUX, a multipoint line can support multiple
independent point-to-point channels.
An optical fiber that supports more than one propagating mode of light
propagation.
Aka. or Multiplexor or Mux,. A device using several communications
channels at the same time, transmits and receives messages and
controls communications lines, may be a microprocessor.
A network-connected device, such as a server or PC.
Voice channel used to communicate between two locations.
A grouping of data, usually consisting of data and an address header
prior to being sent over a network.
The physical access location within a specific location of the long
distance or common carrier.
The method used for terminal to controller communications. The
controller systematically asks for each terminal if it needs to transmit
to the controller.
A set of rules for data communication. All devices communicating
together must adhere to the same rules.
Similar to a bridge but provides more complex and flexible networking
support. It usually also supports WANs.
above the cutoff wavelength.
Network in which all terminals are connected through a single point or
node, such as a star coupler.
Having a constant time interval between successive bits of data or
information.
A type of multiplexer that allocates a defined amount of backbone
bandwidth for each connected device.
Unit of backbone bandwidth allocated for each port.
