Introduction to Collision Domain
In this article, you will learn that what is collision domain and how to avoid it in the ethernet network. In computer networks, the collision domain is a logical area where the data packets collide with each other. In network, when devices compete with each other a collision occurs. When two or more devices access the network, a collision occurs.
Collision domain mainly occurs in the Ethernet and it can mainly be a part of the segment cable, Ethernet hub or the whole network of switches, hubs and other devices.
In the collision domain, only one device is able to transmit the data. When a collision occurs then the devices retransmits the data signals at the later time. The following disadvantages are caused by the data collisions.
- Decreased network efficiency
- Latency
- Packet Loss.
- Slow Performance of the network.
- More bandwidth utilization
- Network Congestion
- Signals Distortions.
CSMA/CD is an efficient way to avoid the collisions in the network. It is a set of rules that tells each network devices like hub, switch and router that when to send the data and when to stop the data transmission. When a computer or network device wants to transmit the data in the network it first listen to the network and see if any other device is using the channel or not.
When the transmission channel is free the data is transmitted. More collisions results in more decreased efficiency in the network. Collision domain main occur in the Ethernet network that is using hubs and it is confined to one subnet.
