what's up guys welcome back to the
channel i'm mike and this is the
ultimate tech hub
and this is our ultimate network panel
and on today's video
i'm going to reveal three things that
your network switch cannot do
and i'm referring to an unmanaged switch
like the one you see right here this
tp-link
and we also have netgear switches as
well
network switches are among the most
important computer networking devices
you can have
a switch joins multiple devices within
one local area network
which is referred to as a lan
switches are layer 2 devices in the tcp
ip and osi models
the main benefit of switches is they
break up collision domains
which impacts your network efficiency
a network switch breaks the preclusion
domain
by learning the mac address of the
devices so that when data needs to be
sent to a specific device the switch
sends it only to the port the device is
connected to
so now that we know
what a switch does
it's very important to know what it
doesn't do
and these are the three things your
switch can't do first your switch cannot
be configured no vlans
and no security protocols
you have zero ability to customize your
switch
and that's why they call these
plug-and-play switches
second you have no ability to monitor
your switch
when something goes wrong on your
network
and eventually something will
there is no way to monitor your switch
however in the event that something goes
wrong
simply unplugging your switch for 30
seconds and plugging it back in usually
resolves the issue
and once again these are plug and play
devices
and the third thing a switch can't do
is break up broadcast domains
like i said before they can break up
collision domains
which is a big benefit over hubs
but they cannot break up broadcast
domains
and you might be wondering what a
broadcast domain is
in short a broadcast domain is a logical
division
of a computer network
in which all nodes
can reach each other by broadcast
at the data link layer
i know this sounds complicated but just
understand
routers and managed switches can break
up broadcast domains as well as
collision domains
and remember there are huge benefits to
an unmanaged switch they're very easy to
use
and they're very reliable
and lastly they're very cheap now like i
said before
if there's any issue with your switch
just unplug it for a little bit and plug
it back in
that solves the problem 99 of the time
well guys i hope you learned a lot about
switches today
especially what they can't do
if you have any questions leave them in
the comments below
i answer all questions
well guys thank you so much for watching
you guys are awesome
you're the best viewers and subscribers
on youtube
thank you again for being a part of our
channel
and we'll see you in the next video real
soon
peace
