What is Collision in Networking? – Detection & Avoidance

Do you want to learn about collisions in networking? If yes, stay on this article because we have covered this topic in detail. And in this article, you will learn collision in computer networking and how it works. We will also discover some brief information about collision detection and avoidance.

So, if you want to get every detail systematically. Please stay on this article and keep reading it step by step.

What is Collision in Networking?

Collision is the condition or the situation when two or even more computers start transmitting electronic signals at a time. And therefore, IT professionals use network accessing methods to handle collisions.

If we talk about Ethernet networking, then a collision can occur if two or more network stations start transmitting the signals in the wire simultaneously. Hence, to handle this, such wires use CSMA/CD or Carrier Sense Multiple Access with Collision Detection method. And it is placed on each station, so whenever any station takes the access of wire, it finds out.

In short, collision in computer networking is the scenario when two or more computers start sending signals simultaneously. And to prevent such situations, such as wire, use CSMA/CD methods.

How Does Collision Work In Networking?

When the station in the network transmits the signal, it is found as a collision. The station will stop transmitting the signal, and it will cause a jam signal. So, the other stations will stop their process from transmitting the signal to other stations. And these stations will wait for a random time interval to start retransmitting the same signal.

So, if there will not be any collision issue, signals get transmitted easily. The collision in-network situation can occur if it is the physical layer in the OSI model. And when there are multiple devices, they share the same media in the physical layer. Then there can be a collision as multiple stations may start transmitting information simultaneously.

What is Collision Domain in Network?

The collision domain in the network is the place in the network where a collision has taken its place. It is the local place in the network that jams the network. In simple words, the collision domain in the network is where the collision error has appeared.

Collision Detection in Computer Networks

Collision detection is the standard issue found in the two or more objects that intersect together. This is the computational error that most commonly appears in computational geometry. However, collision detection can mostly appear in computer games, robotics, and similar components. And because of this, it can be divided into two parts of operating on 2D and 3D elements.

Collision Avoidance in Computer Networks

Collision avoidance is the process that is mainly used in telecommunication and networking. It is the essential thing to do to avoid contention of the resources. Also, using this approach, the situations of a collision or when two or more nodes start accessing the same resources can be prevented. With this technique, the IT professional can ensure that signal transmission in the network passes without colliding with any other traffic within the network.

This method uses carrier detection schemes, randomized access times, and prior scheduling time schedules. Exponential backoff is another excellent method being used as the collision avoidance method.

A collision can also appear in wireless networks, and it also occurs in a wired network. Hence, to avoid such jam issues in the network and make it accessible for smooth flow of information. Collision avoidance methods are great as these methods ensure the free flow of signals. Also, if there is already any signal being transmitted, it will alert another node. And that node will wait for random timing to transmit the same signal again.

Conclusion

So, in this article, we did a detailed discussion on collision in a computer network. We also discussed some other key phrases used in such a context. Hence, we hope now you have a clear idea about collisions in a computer network. And you know it is the situation where two or more nodes start transmitting the signals in the same network simultaneously. And it is the situation that is called collision in technical terms.

However, the area where collision takes place is called the collision domain. Collision avoidance is the method that prevents the situation from occurring in a collision in the computer network. These methods can alert other nodes and ask them to wait until the traffic gets clear. Or there can be other collision avoidance methods to prevent such situations in the network.

Thus, now you have learned in detail about collisions in a computer network. And if you liked this great piece of the article, then do not forget to share it. Also, share your excellent views in the comment section to motivate our efforts.
