Auto-Negotiation
Signalling method allowing each node to select its optimum operational
mode (e.g., 10 Mbps or 100 Mbps and half or full duplex) based on the
capabilities of the node to which it is connected.
Bandwidth

network signals. Also synonymous with wire speed, the actual speed of the
data transmission along the cable.
Collision

other. Their interference makes both signals unintelligible.
