Explain the concept of Collision Domain. Explain why collisions occur in HUBS and Repeaters.

If two computer systems transmit at the same time a collision occurs. The collision with CSMA/CD network is known as Collision Domain.

In an Ethernet network a group of nodes compete with each other for access. If two or more devices transmit at the same time, a collision occurs. Each transmitting-receiving pair of nodes in a switched Ethernet environment has its own collision domain.

While sending the data packets through every other port, a collision occurs.
