Collisions and Collision Domains in Shared Layer Environments

| 5.5.6 | Repeaters and collision domains

Repeaters regenerate and retime bits, but they cannot filter the flow of traffic that pass through them. Data (bits) that arrive at one port of a repeater are sent out on all other ports. Using a repeater extends the collision domain, therefore, the network on both sides of the repeater is one larger collision domain.
