Some people fear birthdays, damn this turned out dark

[@grumpent]

[@manafro2714]

From L1 upwards, they are in alphabetical order: L1=bit, L2=frame, L3=packet, L4=segment.

[@SpiffySpecs]

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.

[@Dgctg3411]

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