What is Collision Domain and Broadcast Domain?

What is Collision Domain and Broadcast Domain?

Fadıl

Collision is called the error that occurs at the same time both during packet sending and receiving. This is especially the case for devices that operate half-duplex, such as Hub and Repeater, that is, cannot send and receive packets from one port at the same time. Collision Domain is the area where there is a collision. In other words, it is a region where a collision can take place. Since Hubs and Repeaters send the packets they receive to all ports, there is one Collison Domain regardless of how many hubs and devices connected to the hub. Routers and switches have as many ports as there are Collision Domains. Because there is only one packet collision probability on each port. Briefly; While there is one collision domain at the hub, the switches and routers have as many collision domains as each port. Therefore, it is better to use switches and routers instead of hubs in professional networks
