transmission of signals without modulation

a signal all of whose energy is contained within a finite frequency range

simultaneous transmission of data to a number of stations

All of the above

resistance to data theft

fast data transmission rate

low noise level

few transmission errors

one or more conductors that serve as a common connection for a related group of devices

a continuous frequency capable of being modulated or impressed with a second signal

the condition with two or more stations attempt to use the same channel at the same time

a collection of interconnected functional units that provides a data communications service among stations attached to the network

a technique used in best-effort delivery system to avoid endlessly looping packets.

a technique used by protocols in which a lower level protocol accepts a message from a higher level protocol and places it in the data portion of the low level frame

One of the pieces that results when an IP gateway divides an IP datagram into smaller pieces for transmission across a network that cannot handle the original datagram size.

All of the above
