In a collision detection network access control scheme a node transmits data on the network:

A) at all times.
B) when other nodes are sending messages on the network.
C) at preset timed intervals.
D) if there are no other messages on the network.

Collision Detection

The computational procedure to check and identify when two or more entities in a digital simulation or physical environment occupy the same space at the same time, to prevent or resolve conflicts.

Network Access Control

The method of accessing the network media (cable) to ensure that data are transmitted in an organized manner in order to reduce the possibilities of data corruption.

Node Transmits

The process by which a node or endpoint in a network sends data or signals to other nodes.
