  • Been trying to wrap my head around this for a long time. Seeing this made it all come together for once. Now I understand it overall, finally! I can delve deeper into it now and understand more when I use wireshark.

  • Is that what you told about session layer correct ? I learnt it as session layer is used for separating one application data from another application data. Its used for security. isnt it like that ?

  • My lecturer used this video instead of explaining the OSI model by himself.

  • you are like a 1000000000000 times better then my teacher, very nice tutorial. thanks a lot

  • What CBT training series is this from? and who is the instructor?

  • Why not do them in order....?

    

  • its not an acronym, its a mnemonic

  • One thing I do NOT like is starting with the last layer and going to the first in your mnemonic. I memorized the OSI layers from 1 - 7, not 7 - 1.

  • @tjl30 Yeah. An amplifier is used to amplify analogue signals when attenuation occurs. When an analogue signal is distorted by such things like Electromagnetic Interference, that too, is amplified.

    When a digital signal is distorted, the repeater will regenerate the signal back to its original state.

  • A repeater doesn't amplify a signal it makes a copy of it. When an analog signal is amplified the data is distorted.
