Carrier Sense Multiple Access/Collision Detect. Carrier Sensing Multiple Access with Collision Detection
[view]

A modulation technique in which the carrier frequency is shifted by an amount proportional to the value of the modulating signal. The amplitude of the carrier signal remains constant. The information signal causes the carrier signal to increase or decrease its frequency based on the waveform of the information signal.

Carrier Sensing Multiple Access with Collision Avoidance
[view]

A multiplestation access scheme for avoiding contention in packet networks in which each station can sense the presence of carrier signals from other stations and thus avoid transmitting a packet that would result in a collision. See also collision detection.
