network load of a segment is contained in the originating segment and does not represent

extra load on the remainder of the network.

On a MDI port or a MDI cable, the receive (Rx) and

transmit (Tx) cables are not crossed over.

Medium Dependent Interface – crossover.

On an MDI-X port or MDI-X cable, the receive (Rx) and

the send (Tx) lines are crossed over.

form of a tree structure that contains all the relevant information for network management in

SNMP.
