Your Way To Better Network Performance
the end of the day, the roles played by a bridge and a switch
are more or less identical - they help to break a network up
into a number of smaller collision domains. Recall from earlier
in the series that a collision domain is simply a group of computers
amongst which data collisions can occur. For example, when connecting
systems using a hub, all systems are considered to be part of
the same collision domain, since the hub will simply forward
data out all ports, with no regard for where the actual destination
host is located.
