collapsed backbone
A network backbone that consists of the backplane of a single switch, rather than multiple switches connected together. From the ports of the single switch, cables connect to the hubs of individual LAN segments.
Collapsed backbones are typically used for mid-sized LAN networks. The architecture is easier to manage, easier to keep secure and less costly as there are fewer networking devices.
However, a collapsed backbone architecture typically uses more cabling over longer distances and a failure in the central switch will cause the whole network to go offline.

- collate
In printing terminology, collate means to print in sets when multiple copies are sent to the printer.
- collision
The situation that occurs when two or more devices attempt to send a signal along the same channel at the same time. The result of a collision is generally a garbled message. All computer networks require some sort of mechanism to either prevent collisions altogether or to recover from collisions when they do occur.
- collision avoidance
A means of proactively detecting whether a node on an Ethernet network can transmit a signal without risk that it will collide with other traffic on the network.
- collision detection
(1) In networks, collision detection is the process by which a node determines that a collision has occurred. Collisions occur with most networks, so a protocol is required to recover from such events. Ethernet uses CSMA/CDas its collision detection and recovery system. (2) In virtual reality environments, collision detection is a program interface that determines […]
- collision domain
A group of Ethernet or Fast Ethernet devices in a CSMA/CD LAN that are connected by repeaters and compete for access on the network. Only one device in the collision domain may transmit at any one time, and the other devices in the domain listen to the network in order to avoid data collisions. A […]
