Man this networks class makes me want to move into a van down by the river. I can't wait for this semester to end. Thank you for the content to help me get through.
been studying from neso academy since I was in my second year of college. This guy is a saviour😄😄. Watching your videos after a while now is bringing back memories of those dreadful semester examination days😂😂Anyways, thank you so much man🙌🙌
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

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.
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...
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.
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.
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 ?
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. 🤗❤️
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?
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..
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.
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)
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.
Correct me if I'm wrong. Let's assume we have two stations A and B, will it be correct to say that when using Go-Back-N ARQ or other ARQ protocols one station is only sending useful data and receiving ACK another is receiving data and sending back ACK. After all frames are sent they change roles. And if this statement is true, how do stations initiate their roles when they have both equal parameters and access to media? Who is the sender at the first step)))? Thanks in advance.
Whenever there is a terror of exams, Neso Academy is standing by us as a savior. Thanks A Lot Neso Team
Facts approved! I am having a Computer Network Mid- term exam this afternoon. Hope this' ll have !

excellent explanation i have watched many videos of many people but this explnation was brief and accurate
Thank you for teaching! I completely understand now and I am ready for my class 2 hours from now lol
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.
Thanks brother.

Really superb 🤩🤩🤩🤩time saving too thankyou so much for helping before exams
Super explaination 🔥🔥 TQ
I Love U! you explained it so easy and light to digest. keep up the good work and i wish blessings upon you
10:30 what about 3?
why only ignores 4 and 5, 3 was also already sent.
3 will also be ignored
then about 2
@@yummycandy1703 2 wasn't acknowledged so it is being retrasmitted along with 3 4 5
Very clear explanation. Thank you!!
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 ?

Good morning

Thankyou so much sir for this wonderful explanation ❤class mae ghanta kuzz smj nhi aayea tha
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 🥲
if i took a shot every time this man said GO - BACK - N ARQ i'd be on the floor dead
Nice explanation😊 Thanku so much
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 !!!
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)
Crystal Clear Explanation!!
Towards the end, you mention that the receiver did not get frame 2. That is not consistent with the timing diagram.

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 !!
best explaination for go back n arq.

Sir please make a vedios lecture on Microprocessor .full playlist of Microprocessor
Thank you so much sir 🙏
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
God bless you
You are awesome💘
Superb video 🌟
Thank you so much tomorrow is my exm 🥺
ack of frame 2 not recieved so frame 3,4,5 will be discarded and retransmitted with frame 2 again ? 9:41
Nice explanation bro. Please write and explain program also bro..
Perfectly understood
Well explained
Very helpful. Thank you so much

have exam at 2pm
watching this at 1pm 🎉
ideally it should discard frame 3,4,5 for our example if 2 is lost and not received by the sender.
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.
I hv exams today at 2 pm and i am watching these videos
Sir please release video lectures series on 'EM theory and transmission lines' for gate - 1000 times thanks sir in advance !
it could also use a bit sequence number with a window size of 4 right? like 0,1,2,3,4,5,6,7
10:30 frame 3 also be discarded ryt..it is retransmitted
Having exam in 5 mins
If I correct then 3 4 5 are discarded by receiver instead of 4 and 5.
