A collision occurs when a station begins transmission and then receives the beginning of a frame from another station..."*

"A broadcast domain is a restricted area in which information can be transmitted for all devices in the domain to receive. More specifically, Ethernet LANs are broadcast domains. Any devices attached to the LAN can transmit frames to any other device because the medium is a shared transmission system. Frames are normally addressed to a specific destination device on the network. While all devices detect the frame transmission on the network, only the device to which the frame is addressed actually receives it. A special broadcast address consisting of all 1s is used to send frames to all devices on the network. A repeater is a device that joins two LANs to extend the distance of the LAN. All network traffic is sent across the repeater unaltered..."**
