collision domain

Collision domains are also found in wireless networks such as Wi-Fi.

Collision domain, a physical network segment where data packets can "collide"

Using network switches allows the network to be broken up into many small collision domains.

Bridged networks break up collision domains, but the network remains one large broadcast domain.

Collision domains are generally smaller than, and contained within, broadcast domains.

A switch breaks the collision domain but represents itself as a broadcast domain.

This rule is also designated the 5-4-3-2-1 rule with there being two network segments and one collision domain.

In contrast to an Ethernet hub, there is a separate collision domain on each of the switch ports.

An Ethernet network may be divided into several collision domains, interconnected by bridges and switches.

The entire network was one collision domain, and all hosts had to be able to detect collisions anywhere on the network.

The rule does not apply to switched Ethernet because each port on a switch constitutes a separate collision domain.

The distinction between broadcast and collision domains comes about because simple Ethernet and similar systems use a shared transmission system.

One way to reduce congestion would be to split a single segment into multiple segments, thus creating multiple collision domains.

Layer 2 switching is used for workgroup connectivity and network segmentation (breaking up collision domains).

A network with a large number of nodes on the same segment will often have a lot of collisions and therefore a large collision domain.

When using a hub, every attached device shares the same broadcast domain and the same collision domain.

In full-duplex mode, both devices can transmit and receive to and from each other at the same time, and there is no collision domain.

A unicast frame is transmitted to all nodes within the collision domain, which typically ends at the nearest network switch or router.

This means there is a unique frequency used for each wireless hop and thus a dedicated CSMA collision domain.

This is as compared to a collision domain, which would be all nodes on the same set of inter-connected repeaters, divided by switches and learning bridges.

According to the original Ethernet protocol, a signal sent out over the collision domain must reach every part of the network within a specified length of time.

This mechanism is only utilized within a network collision domain, for example an Ethernet bus network or a hub-based star topology network.

Thus, the broadcast domain is the entire inter-connected layer two network, and the segments connected to each switch/bridge port are each a collision domain.

Single and dual-radio mesh use proprietary means to repeat the signal which means that more than two nodes are in the same collision domain and frequency.

This rule divides a collision domain into two types of physical segments: populated (user) segments, and unpopulated (link) segments.
