ek nyeu teuman.wkwkwkwkwk

1:37 Thank You
-
ANAL.
-
Anal! lol. And a nicer diagram to go with it. I see what you did there ^^
-
all presidents say they never did pot
-
Please Do Not Touch Sophia's Private Area. (If you know what i mean)
-
I thought his cursor was drops on my ´screen -.-
-
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 -
dude just get your self a BOARD
-
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.

Suplement:
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!
-
Think again!
-
Computer is really important to the world, we need to improve the world by moving technology to another level
-
fuck,,,
-
woo this is Bucky Roberts
-
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.
-
great!
-
nice
-
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.
-
not clealy explained
-
oh shit ive never laughed so much anal lol
-
you could have explained the layers of osi more precisely thanks anyway
-
anal :::::NEW NETWORKING SIGNAL ,,,,—–THAT IS ALSO ABOUT INTERCONNECTEDNESS
-
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++
-
pineapple express…AWWW YEAH IM GETTING HIGH ON THIS INFORMATION.
-
Anal, and penis looking shapes…. This would look awkward for me if someone walked by
-
Thank you very much
-
Is dis statement TRUE a hardware on network result=1 ie +v
& -0 hardware on software -
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 ??
-
ANAL WAVES
-
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.
-
excellent video.very helpful for beginners like me.thanks a ton
-
interesting……..thanks guy
