auto-negotiation
A feature on twisted pair ports that allows them to advertise their
capabilities for speed, duplex and flow control. When connected to a
port that also supports auto-negotiation, the link can automatically
configure itself to the optimum setup.

bridge
A device that interconnects two LANs of a different type to form a
single logical network that comprises of two network segments.
