Now we would have 8 collisions in our one broadcast domain. Would you think our link
between the switches be considered a collision domain too? Gotta say no here because
switches have the ability to store information and send it off later (geek speak: queueing).
Therefore no collision possibility exists.
Now that we have multiple switches we have the possibility for excessive
broadcasts that could slow our network down. Ok…with three or four workstations on
each switch it would never get that bad, even with Novell, but cut me a break here ok?
We could use a router to reduce our broadcast domain size. Each interface on a router, in
fact, is its own broadcast domain. So let’s add a router into our network. Here we would
have eight collision domains and two broadcast domains.
