Hello and welcome back to I see anyone interconnecting Cisco networking devices Part one.
This is less an introduction of 1.2 fundamentals of Ethernet lands or local area networks. I am trending Daryl and I will be your instructor for this course. The last lesson we talked a lot about the TCP I pee stick in the OS. I model
in this lesson, we're gonna be covering the small office home office,
land, the enterprise land,
the Tripoli cable standard
cable standards and the penance. Different look, a different categories of Ethernet cables.
The twist rates
different ways that you can crimp a r g 45 cat cable
an episode 1.2 dot three We're gonna look
the parts of an Ethernet frames, right. You're gonna break it down into the different sections and we're gonna go over what each portion is and what it does.
And to include that we're gonna learn about what a mag addresses, how the it is determined and also how you can find it on your own device.
In episode one dot to 1.0.4 we're gonna be looking switches and hubs, the different transmission modes that they use and how specifically the hubs use closing detection.
We're gonna jump in with the pre assessments for this lesson
so real quickly. What is the standards defined for fast Ethernet over you tp. And I'll give you a few seconds to go ahead and pause a video and try and find it.
All right. If you guessed 100 based T, you would be correct. If you look at 1000 base T that is actually gigabit over Internet
or G P
and 1000 Base LX is given over fiber
and then 10 based. He has just Ethernet over you to pee.
So the base Ethernet standard,
the next pre assessment question is give me looking at the second lesson or second episode. What is the typical pin out for a straight through cable?
So there's two answers for this one. So
I'll give you a few seconds to go ahead and try and think of it
and, um, posit video when you're ready.
All right. Hopefully you guys, this one as well.
Both sides should be the t I a 5 68 Bravo.
Do you see through in that diagram there you're looking at pins. 123 and six
should all be the same.
And the last pre assessment question here, What happens to ah ha when it receives a frame
and, as always, will give a few seconds pause video.
All right, so get to the answer, is gonna send it out all the ports, except for the one it was actually received on.
that for hugs, that is what it does. Because physical air device and a switch will actually only send it out the destination port once it learns the Mac address.
And the next episode, we're gonna be looking straight at the small office, Home office or SoHo versus Enterprise lands. You know what the cable pen outs and standards that are used today.
Thank you for Washington. Unless an introduction here.
And as always, if you have any questions if you need any help, go feel free to contact me.
Thanks for watching and look for it. A senior and next episode
This course will enable students to understand virtualization and cloud services, and network programmability related to LAN, access and core segments.
