ViewSonic Wireless Media Gateway 83
Collision avoidance. A network node characteristic for proactively
detecting that it can transmit a signal without risking a collision.
Crossover cable. A special cable used for networking two
computers without the use of a hub. Crossover cables may also be
required for connecting a cable or DSL modem to a wireless
gateway or access point. Instead of the signals transferring in
parallel paths from one set of plugs to another, the signals
"crossover." If an eight-wire cable was being used, for instance, the
signal would start on pin one at one end of the cable and end up on
pin eight at the other end. They "cross-over" from one side to the
other.
