Studying for the Network+ and this video was a huge help in breaking down in further detail, what a PDU really is.

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.

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
