Both bridges and switches learn the port to use to reach a MAC destination.
If they haven't learned it yet, they flood the frame out all ports except
the originating port.

Stop right there. It can't figure out that the destination is on a
different subnet from the MAC address. Subnets are differentiated b
There are a few things wrong with that description.
First, switches and/or bridges are layer two devices and wouldn't be
aware of different IP subnets in the first place. A switch or bridge
will forward a frame out all ports except the originating port if it has
not yet learned the correct port
I was under the impression that, while a switch is often termed a multiport
bridge, there is one fundamental difference in the way the two devices
forward frames. While my source is not always the most credible or reliable

No, I think the discriminator is 15 ports. Just KIDDING! Seriously,
assigning a number is not necessary. Most bridges had just two ports, but
there probably were a few vendors that
And it's worth mentioning a couple other things too, just to confuse
matters. ;-)
Although a switch behaves like a multiport bridge, it is often placed in a
topology where a hub used to go. Because a switch has so many ports, people
use them to connect individual stations. Bridges were rarely

Bridge supports up to 16 ports ans is software based.
but Switch supports any number od ports and is
hardware based.

This begs the question, what is the difference between a multi-port bridge
and a switch? Or, what is a switch when it routes? I personally think
bridge and router convey with relatively little ambiguity the function of a
device whereas switch is simply a tool that marketing folks use when th

it's all pretty much the same.

Switching is a marketing term. You would be wise to focus on Bridging and
Routing and when the word switch appears, read to fine print to figure out
if the device in question bridges or routes.

A switch is a multiport bridge. Think of a bridge that bridges together
2 networks (i.e. has two interfaces, one in each network). Then
supposed you upgrade to a 3 port bridge, that can connect 3 networks.
keep adding ports up to 4, 8, 12, 24, or even 48 and that's a switch.
The
Marketing! A switch is simply a multiport bridge. Bridges originally
had very few ports, as few as two. When hardware became faster and
manufacturers started adding more ports to their bridges they started
calling them switches to differentiate them from their slower brethren
with fewer ports.
Could somebody will please describe me the difference in
between bridge and switch.
Thanks
