forward data packets much more efficiently
by sending them only to the devices that need
to receive them. Multiple data packets can
pass through a switch at the same time.
Among other things, this means that switches
have a significantly higher total bandwidth
(throughput) than hubs. Moreover, switches
learn which stations are connected to which
ports, meaning that additional data transfers
will not result in any ports being subjected to
unnecessary loads, i.e., that data will only be
forwarded to the port connected to the inten-
ded destination. With the exception of their
higher price, switches are superior to hubs in
every way.

WINS
Windows Internet Name Service, Name res-

order for this service to be used, there must
be a WINS server. If there is no WINS server,
names will be resolved using broadcasts and
other mechanisms. A fixed name can be
assigned to an IP address in WINS so that a
computer will continue to be recognized even
if its IP address changes.
