    Dude what if we want to send two 1 together like 11011

    All – Application Layer
    People – Presentation Layer
    Seem – Session Layer
    To – Transport Layer
    Need – Network Layer
    Dominoes – Datalink Layer
    Pizza – Physical Layer

    He laughed at Anal. lol
    Thanks for the video

    anal = analogue. genius 🙂

    Binary representation in Analog signals isn't like that ! you can never transmit a message if it's like what you said, negatives and positives of the signal represent one state per each cycle. Modulation is used to do so.

    Hay pal, nice work thanks… can u help me out I also wish to teach online as you do. but am not getting the software to scribble and record.. can you suggest the software u r using..

    dicks pointing to the anal.

    Send data node >> node.
    Its transmitting in dig or ana.
    Digital. Digit. Binary. Only 0's and 1's.

    If you want to send an analog signal
    (exam. [shortcut] microphone >> file) it have to be quantized.

    ADC(ana dig converter) and DAC(dig ana converter).
    Shannon-Kotielnikow-Whittaker-Nyquist law.
    Check Quantization on wiki.

    Same about wireless. Signal from smartphone or by wifi:
    device(dig) >(ana)> BTS or Access Point >(dig/ana)> server(dig).

    Coaxial Cable work>>the signals are going to be transmitted through the "Copper Core", these signals do not move in a straight line because of the bends of the cable then the "Woven Copper Shield" turn comes in to reverse the signal to the "Copper Core". So continuously, the signal is going to lose energy on every reverse..Is this this Correct or not?!

    You are wrong in so many levels, radio is not analog (see DRM), fiber optic doesn't have to be digital (You can send different intensities of light) you are confusing people, in one hand we have physical cables, radio-waves, microwaves… (The physical stuff used to transfer information from A to B) in the other one you have how you use that physical stuff (by sending an analog or digital signal)

    cant stop laughing 🙂

    Was it necessary to place at cable at that angle?
    Distracted 😐

    nice video, thanks!

    Computer is really important to the world, we need to improve the world by moving technology to another level

    woo this is Bucky Roberts

  22. KnightZ1987 Avatar

    In regards to the analog signal, is the wave counted as 1 when it hits the line or crosses it. Im very confused. Can somebody help?

    7 layer model has now been replaced by a less complex 4 layer model.

  24. Cryptoxicon Avatar

    Physically, there is an electrical, modulated signal that is being passed through the wires and converted by an analog-to-digital converter (ADC) so that the computer can interpret this data in ones and zeroes. So basically you have converters on both ends (receiving end – ADC and sending end – DAC). Actual transmission in physical layer through wires is in an analogue form.

    Where did you learn your stuff? Im interested in going to school for computer networking and was just wondering if you had any good places for me to apply to.

    oh shit ive never laughed so much anal lol

  27. jill pandya Avatar

    you could have explained the layers of osi more precisely thanks anyway

    I never knew Bucky is into networking as well , i didnt read the name of the chancel but from the first word i heard i knew it was him i was like WTF Bucky is here as well ? i know his voice bcoz i watched over 50 videos of his on C++

    Anal, and penis looking shapes…. This would look awkward for me if someone walked by

    Is dis statement TRUE a hardware on network result=1 ie +v
    & -0 hardware on software

  33. KharaniProud Avatar

    we will never forget the name of Analog=Anal . This should be the teaching style. We highly appreciate that LOL .

    good work Bucky ! dont you have a tablet for drawing ??

    the technologically challenged association (me) proudly presents to you the Awesome Guy of the year award. Your videos are like finding a pair of inflatable arm floaties in an ocean of "wtf did that dude/chick say?" videos… I think I love you… Nerds are strait out sexy.
