Which is used to break the collision domain in switched network?
Explanation:
Switch have single collision domain at each switch port. A collision domain is a segment that is shared by a connected medium through repeaters and data may collide with each other while sending or receiving. It is applicable more in wireless networks however this was also present in wired network as well. Collision occurs when multiple devices tries to send data in the same network segment at the same time. While sending the data, probability increases that the data may collide with each other. If we have to avoid collision, then only one device may send and only one device may receive and by following this process we can avoid collision. Increase in collision will directly impact the efficiency of the network as the device might have to retransmit the lost packet multiple times.
