a collision domain is as the name implies a part of a network where packet collisions can occur a collision occurs when two devices send a packet at the same time on the shared network segment the packets collide and both devices must send the packets again which reduces network efficiencyollisions are often in a hub environment because each port on a hub is in the same collision domain by contrast each port on a bridge a switch or a router is in a separate collision domain
