Studying for the Network+ and this video was a huge help in breaking down in further detail, what a PDU really is.
Some people fear birthdays, damn this turned out dark
Yes indeed
I just thought it meant they forget more often, bruh now it's dark 💀
From L1 upwards, they are in alphabetical order: L1=bit, L2=frame, L3=packet, L4=segment.
..I have landed on this today
It's my best
Thank you sir
You deserve a sub
I love your video. It's very informative. I'm currently learning Network+, but I still don't understand why the PDUs are needed. Why can't we just send the data as is? Please keep making more of these videos.
The way you teach es incredible. I love it😃
Thankyou Mr Barker for the lessons.
Nice. In Germany we call the birthday part an "Eselsbrücke" (Donkey bridge). Silly small sentences who burned in your mind and you probably never will forget :D
This was amazing 🙌🏽
good to see you with Cisco Mr Barker 😀👍
6 years old, still great resource. remember kids, Bigfoot Fought and Pummeled Sticky Dragons 🤣
Great Video! Thanks, Cisco!
Good to see you, Keith.
thanks for the class. please continue to share knowledge
This guy sounds like Tony Hawk if he became a nerd instead of a skateboarder
Hmm it's a good lecture indeed 😀😀

Great teaching
i wish this guy was my teacher

Thank you, that was helpful.
NAME THAT PDU!!!
WAO THAT WAS SO INTERESTING AT THE END
some people fear birthday lol
Nice video.
Why did it take 6 minutes to get 30 seconds of information? 😑 Imagine a whole course like this. Thanks either way
Offer some mnemonic to logging levels which is more handy;)
This is the point where I ask myself: What exactly does Cisco do? I thought you are a software company and that you only have webex... But turns out you do research?
What's his name?
