Ethernet
A widely implemented local area network (LAN) protocol that uses a bus or star topology and

layers. Baseband LAN allows multiple station access to the transmission medium at will
without prior coordination and which avoids or resolves contention.

A numeric code that displays in the event log. This code provides information on system
failures, such as hardware failures, failure locations, or general information on normal system
events.
