The land and when particles those work at layer then lastly we have the
other physical layer this is going to be the actual physical properties in
the media so when I'm connecting two switches together do they connect
over copper or do they connect over our fiber so this would be like your
electrical functions at like or the other physical data rates when I look
at even at that run sat a megabits per second for Fast Ethernet races
Gigabit Ethernet at gigabit per second that's going to be a physical
electrical function up the link how often I actually send the other pulses
on the interface hey this is where you would also defined the now the
physical connectors so when I have the fiber cable plugged into the router
what is the actual are connector that I physically pluginthis different I
to standards that are going to are defined this will also be in are how
far can you send the traffic over the cable so I need this in my data from
New York all the way to Los Angeles over one physical link then the layer
properties are going to come into play so if it's as if it's a electrical
signal over copper interface typically that's not going to work because
the signal can go that far so this would be are different the physical
functions at the actual cable like the on the optics or the I like the
optical wavelengths and in the case a wireless this is going to be your
frequency like when we talk about the difference between that b were g
and Anna they want different a wireless frequencies in order to send and
receive the data but in this case that would be considered a physical
function where in the case even at your physical media might be your
copper cable but in the case a wireless your physical media is the air as
though the radio frequencies exchange between so again this is where our
cables are going to be and then some physical layer devices will talk
about [http://646-206dump.com/ 646-206] later up for internet are
repeaters and Hobbes where basically these are obsolete devices no I
wouldn't be surprised if on the CCNA exam more like this season exam day
ask you specifics about the different layers so this is typically one of
the things you can't get away with not memorizing what.
