Nice. Indian letures are the best. I'm not used to with Indian English but there is sub available so I was still able to understand. Thanks for knowledgements!
I sat for half an hour listening to my professor 😹😹 i didn't understand accept the heading..but when u detailed the concept by showing the animation within a fraction of second I was able to understand thanks a lot
one of the best explainations one can get get on youtube....please let me know if you guyz have a proper course,...i would love to do it...ineed certification and project...
students definetley like your explanation the way you explained and most importantly and the begning and ending you are adding outcomes thats an important one to students better sir. we have no fear because you are here to explain us . once again thank you sir
at 5:10; what ll b sequence number if we have the window size n=3,, which can not be represented in power of 2?? In this case what should be added or subtracted for the sequence number.
It may be important to add, that if ACK 2 is lost but the sender still recieves ACK 3, he knows that the receiver actually recieved PCKT 2 even if he didnt receive the acknowledgement for it. So he will not resend PCKT 2.
that's would be right if it's explicitly mentioned that we are using " Including acknowledgement " : which means we acknowledge all previous frames the sender has received and not every frame individually. For example, if ACK n is received by the sender, it means that all frames ( from 0 to n-1 ) are marked as received. Even though it's not the case by one of the frame ( frame get lost ).
I guess, As soon as the time's out(in waiting for acknowledgement of Frame2), the next frames i.e., Frame3,4,5 which were already sent are discarded ..So, the receiver will not receive any frames and thereby it can't acknowledge.

Thanks for the video. You should also include timers like start timer, restart and stop timers according to packets sent/Recived or lost, the timer concept i also important to understand.
Great short lesson, you were very clear and easy to understand. However, I'd like to point out that in the example you provided there's an error: GbN uses cumulative ACKs, meaning if ACK (packet 2) is never received, but ACK3 is received, we assume that ACK2 was lost but the packet itself was received.
Omg,,, I clearly understood this. I was looking for some tutorials before my exam and I m lucky enough to find this channel. Thank you so much. Explanation is crystal clear. 🤗❤️
as you said that the frame 4 and 5 are discarded by the receiver because the frame 2 was lost, after this frame 2, the frame 3 was also sent, what about that ? is that also be discarded by the receiver ?
11 minutes of your video explaining is better than my professor full 4 hours lecture session. Bad lecturers will tell you to self learn despite the expensive tuition fees we paid them. Well, by using self learning as an excuse, this caused more and more professors degrade in their teaching. Sounds good huh?
It can be anything, it's just that in order to represent we find the nearest power of 2 (which may be greater than or equal to the number to be represented)
We can find all the topics online but you will find the well organized playlist very rare.. Till Now I have completed from 1st video to this 61st video.. I hope I can complete this as soon as possible..
Towards the end, you mention that the receiver did not get frame 2. That is not consistent with the timing diagram. Frame 2 is actually received, it is the ACK for frame 2 that is lost, so when the sender times out, it sends 2,3,4,5 and because the receiver in Go Back N can only receive in-order frames, that is why the initial transmissions for frames 4 and 5 are discarded.

best explaination for go back n arq.
At 5:36, So window size must be power of 2 only or it can be any other
It can be anything, it's just that in order to represent we find the nearest power of 2 (which may be greater than or equal to the number to be represented)
Superb video 🌟
Thankyou so much sir for this wonderful explanation ❤class mae ghanta kuzz smj nhi aayea tha
Thank you soo much sir for simple explanation ☺️
what about the frame 3, is it discard or not. Because frame 3 still in the window as well as sender side. So, only 4,5 are discarded or 3,4,5.
same doubt 🥲
Super mowaa super ga cheppav
if i took a shot every time this man said GO - BACK - N ARQ i'd be on the floor dead
Thank you so much tomorrow is my exm 🥺

Is frame 3 also discarded? I think he missed that
@@nomen385 Yes, anything out of order is discarded.
@@nomen385 yes i also felt the same thanks !!
God bless you
Nice explanation bro. Please write and explain program also bro..
Thank you so much sir 🙏
Perfectly understood
please upload transport and other layers
9:25, why isn't 3 also being discarded/ignored?
It is discarded, he just forgot to mention.
@@B3jn Thanks I have the same doubt.
ack of frame 2 not recieved so frame 3,4,5 will be discarded and retransmitted with frame 2 again ? 9:41
Having exam today afternoon 😂😂
Same after 1 hr
Same after 25 minutes
have exam at 2pm
watching this at 1pm 🎉
@ 3:26 transmitted or retransmitted ???
Very helpful. Thank you so much
Thank you so much 💓 💗 💛 💖 😊
Well explained
Y don't u ppl start the online college, give a degree🙂
However even these colleges r also taking online classes itself.😒
Thats was nice idea !!!
1000% correct way....
10:30 frame 3 also be discarded ryt..it is retransmitted
Sir please make a vedios lecture on Microprocessor .full playlist of Microprocessor
Good explanation
Amazing ❤
Awesome .. Thankssss
Thanks a lot.
Best one ❤
i think the receiver will also discard the 2and 3 because they are already there as the ACK is lost but the receiver had that frame 2 and 3
