The protocol used by wired Ethernet to manage frame collisions is carrier-sense multiple access with collision detection (CSMA/CD).
Ethernet is a networking technology that is based on a shared medium, which means that multiple devices share the same physical connection to transmit and receive data. When two devices try to transmit data at the same time, a collision occurs, and the data becomes corrupted. To prevent collisions, Ethernet uses the CSMA/CD protocol.
CSMA/CD works by having each device listen for traffic on the network before transmitting. If a device detects traffic on the network, it will wait for a random amount of time before trying to transmit again. This helps prevent multiple devices from transmitting at the same time and causing a collision.
However, if two devices do transmit at the same time and a collision occurs, CSMA/CD is used to manage the collision. When a collision is detected, the devices that were transmitting stop transmitting immediately and wait for a random amount of time before trying to transmit again. This random wait time helps prevent the devices from colliding again.
Overall, CSMA/CD is an essential protocol for wired Ethernet networks as it helps manage collisions and ensure that data is transmitted successfully.
