What occurs when a collision happens on a network?
We know the data can be sent through a device to the other device. But, do you actually wondered how the data get transferred from device to device without any interference in between? When a network consists of a lot of computers, then there be a lot of data traffic that needs to be sent. During the transmission of the data from one device to the other device, the collision occurs between the two devices. The data packets may hit each other in the network traffic.
This causes a collision between the two devices. Many collisions may happen frequently, mainly in older networks. We have introduced different technologies to avoid the collision between the devices.
When the collision occurs, the data or information cannot be received on the receiver side of the network. So, to avoid collision and to transmit the data correctly even though the collision occurs, the CSMA/CD is introduced. The CSMA/CD stands for carrier sense multiple access/collision detection.
This method is used on Ethernet networks. To understand the concept of CSMA/CD, let us take an example, suppose we have multiple computers when multiple computers want to send data to the multiple devices at the same time, all the systems must be regulated and no computer should send the data at the same time, if the collision occurs, it causes a data loss in the network.

When a computer wants to send the data to the other device, the sender device checks or senses the data traffic in the cable in which all the systems are connected. If it detects any data transfer in the cable, the sender device waits until the cable becomes idle.
After the sender system finds there is no data traffic in the cable, it starts to send the data, while transmitting it listens whether the collision is occurring in the network cable.
I hope the answer given for the question “What Occurs When A Collision Happens On A Network?:” is clearly understable.
