Networks
Technologies - Ethernet (3 of 3)


An important Ethernet specification is the way in which the network handles collisions that occur when two computers transmit packets at the same time.
A computer will send a packet if it thinks the network is free; if another computer sends a packet at the same time a collision will occur.
The first computer sends a jamming signal to ensure that all the other computers on the network detect the collision and then, after a random time delay, it tries to send the packet again.
