event of a power failure, a disk crash or a major user error, data is not lost and the
system can keep running.
FRAGMENT-FREE FORWARDING
A type of forwarding method used in switches that allows data to be forwarded
through after the first 64bytes of each data packet is checked due to the data error
rate condition of the network.
FULL DUPLEX
Transmitting and receiving data simultaneously. In pure digital networks, this is
achieved with two pairs of wires. In analog networks, or digital networks using
carriers, it is achieved by dividing the bandwidth of the line into two frequencies,
one for sending, one for receiving.
GARP VLAN REGISTRAION PROTOCOL (GVRP)
Defines a way for switches to exchange VLAN information in order to register
necessary VLAN members on ports along the Spanning Tree so that VLANs
defined in each switch can work automatically over a Spanning Tree network.
HUB
Central connection device for shared media in a star topology. It may add nothing
to the transmission (passive hub) or may contain electronics that regenerate
signals to boost strength as well as monitor activity (active/intelligent hub). Hubs
may be added to bus topologies; for example, a hub can turn an Ethernet network
into a star topology to improve troubleshooting.
