Detailed explanation-1: -A network collision occurs when two devices attempt to transmit data on a shared circuit. In a shared circuit where multiple devices are listening, only a single device can transmit data at a single point in time which requires the rest of the devices to be listening to the transmission.
Detailed explanation-2: -Packet collisions happen when two or more network nodes attempt to send data simultaneously, resulting in collisions and possible loss of transmitted data.
Detailed explanation-3: -In a half duplex Ethernet network, a collision is the result of two devices on the same Ethernet network attempting to transmit data at exactly the same time. The network detects the “collision” of the two transmitted packets and discards them both. Collisions are a natural occurrence on Ethernets.
Detailed explanation-4: -A collision is an event that happens on an Ethernet network when two stations simultaneously “talk” on the wire. Collisions are a normal part of life in an Ethernet network, and under most circumstances should not be considered a problem.
