@@morgard211 I don't know what you are talking about. I started studying from Neso Academy and find it really interesting. Always wondered, how these communications happen.
the presentation you are doing. it took lot off time to prepare. such a hard you are doing for free course. thank you so much for making these video. it helps me a lot
4:18 *CORRECTION:* The sliding window does have significance. The erroneous bit is sent AFTER the sender window is empty. It sends the erroneous bit and continues where it left off. Meanwhile the receiver sends NACK of the erroneous bit with every ACK of subsequent bits.
Today is my exam and I thought that stop and wait protocol is so boring and tough to understand and prayed to god that please don't ask questions about this topic in my exam but after watching your video now I changed my mind and pray to god that please ask at least one question in my exam of 5 or 10 marks. Thank you so much.
How does the sliding window slide when frame 2 is not acknowledged? and Why the sender won't send a new packet when frame 3 is acknowledged but wait for frame 4 to be acknowledged to send frame 6? Thank you.
So from my understanding at 4:10, frames outside the window (like frame 6) can still be sent? Even if the window is waiting for frame 2's acknowledgement to proceed?
I thought that subject is boring. But no... The fault is not in the subject, but it's in the professor. Thanks for ur effort, so that we can effortlessly write our exams.🙏🙏
actually the fault isn't in subject nor in teacher but in ourselves. if one has interest in any subject, he/she will put efforts to gain knowledge even without a teacher.
@@oggy107 yes but the prof should make the subject interesting while introducing it. A student cannot be interested if the prof can’t explain exactly what’s going on. Something which neso academy does very well.
If frame 2 is lost, then receiver window should wait for frame 2, and then when timeout occurs on sender side, it will send frame 2 and then on receiving frame 2 on receiver side, receiver will acknowledge and will slide the window by 4 because 3,4,5 are already stored. On sender side on receiving acknowledge of 2, it will slide the window by 4. Is this correct?
If frame 2 is lost and frame 3,4,5 are received, the receiver window is not moved forward. The reciveer will simply put 3,4,5 in the buffer. When it receives frame 2 , it groups and delivers 2,3,4,5 and moves the window forward by 4 frames ( because a total of 4 frames were delivered).
What is the concept about negative acknowledgement ? Imagine if the acknowledgement is lost, then does the sender assumes it by default as negative acknowledgement ?
Do you know why the hell is my homework asking for the difference in window size between Selective Repeat and Go back N given the same number of bits for sequence number? I don't see why there would be any difference in the window size between the two.
Assume that two computers A and B are connected with 512 Gbps bandwidth. Consider if the distance between the hosts is M metres and the link speed of the medium is 2 x 109 m/s. If Computer A need to send a one- kilobyte packet to Computer B. What is the minimum distance M required such that the propagation delay equals the transmission delay?
I slept through the entire semester on this subject because I find it boring but you made it interesting, thank you!
networks are boring af :/ gladly I won't have to hear about them if I succeed in the exam

@@user-mi8ew2to8e well it's very subjective
@Shreevatsa Bhat what about mss, I didn't remember a single from that subject.
@Shreevatsa Bhat No that would be software engineering,compiler design,microprocessors and microcontrollers.
Our Community Is Better Because You Are In It.Thanks For The Videos😌
The best instructor in neso academy I have seen in this computer networks playlist thanks for this content 🙏🙏🙏🙏
Watched your all videos which are based on protocols. Now, I am crystal clear what actually protocol is 💯
the presentation you are doing. it took lot off time to prepare. such a hard you are doing for free course. thank you so much for making these video. it helps me a lot

Would you make it more clear i didn't get you?
Same, would love some clarity.

I'm very thankful for your videos. I know I can seem crazy but content like yours are heritage of humanity.
I felt this subject interesting after watching your videos.. thankyou so much
A great and super concise explanation! Thanks!
sir carry on , i told my friends to watch yours videos..pls upload more videos on this subject
Please upload more videos on computer networks, want to study more on computer networks during lockdown period.
thnx mann your video helped me covering syllabus just a night before my exams
Best video in order to prepare at the time of semester
The presentation your are doing takes a lot off time to you. thank you so much for providing free content like this.
i got back in this sub hope these lec helps in clearing my back
Shame on you 😔
Why shame man its a part of life idiot..
How does the sliding window slide when frame 2 is not acknowledged? and Why the sender won't send a new packet when frame 3 is acknowledged but wait for frame 4 to be acknowledged to send frame 6? Thank you.
Dude, but it has sent for 3, and not for 2. So, as per the sequence num, it sends nack for 2, and the others are normal
I appreciated you .becaouse Your lectures are very amazing
So from my understanding at 4:10, frames outside the window (like frame 6) can still be sent? Even if the window is waiting for frame 2's acknowledgement to proceed?
thank you for my help, tutor. i used it.
JazakAllah for this easy and wonderful lecture on this topic.
May Allah gives you more knowledge.

@@oggy107 nah bro. It's the teacher's fault💀. You can't force desire on boring lectures

i love this account. thank you so much for the great videos and excellent explanations ! :)
Thanks a lot yaar❤.It helps a lot for my semester preparation.
Lovely and complete 💯 thank you so much 😌💗
my professor is teaching us CN from your videos and make it look like they made that video
but anyways your videos are great
Thank u sir. Good content and presentation 👍
Mast kaam kr rhe hai aap maja agya❤✌
Very nice explained good concept in less time 👍👌
Would sender send 6 first before getting aknowledge of 2(2nd time)?
Thank god for indian IT youtube
Thnak You very much Sir!!
Tomorrow my exam tq bro
Thank you sir understand extremely with your leature
Thank you so much 💓 💗 💛 💖 ☺️ 😊
Best explanation, thank you
Ur teaching is amazing sir, thq
such good explanation.
I need 4x speed for your videos!
ABSOLUTE LEGEND!
Please upload data structures videos
Good video. so helpful , thank youu
Wonderful Tq
Really impressive teaching 👌
Why didnt you slide the window at all? I thought it would after 5 was ack and frame 7 was sent?
Great channel
Easy to understand!
Thank uhh sir ❤️
Thanks sir😊😊
Thanks alot.It was helpful
thank you 😇 watching it 10 min before exam😅
Hello sir!!....
please upload and continue the videos on power systems.
This is my sincere request.
Can't thank enough!
thank you very much
excelent work!!!!!
Thanks a lot!!

What is the concept about negative acknowledgement ? Imagine if the acknowledgement is lost, then does the sender assumes it by default as negative acknowledgement ?
Sir what is the window size in selective repeat
As said in video,there is no significance of window size and only corrupted packet is retransmitted
Do you know why the hell is my homework asking for the difference in window size between Selective Repeat and Go back N given the same number of bits for sequence number? I don't see why there would be any difference in the window size between the two.
why is the sender able to transmit the pkt 6 even it haven't got the ACK2? shouldn't the sliding windows is locked on the position of pkt 2~5?
Refer Behrouz Forozan and Tanenbaum, these videos are abstract and don't delve in detail.
God for engineering students❤❤
where i can find all these PPT's or the notes for the same
Tq 🎉❤❤❤❤
thank you
Is Selective Repeat better than Go-Back-N in time performance?
Thankyou
Assume that two computers A and B are connected with 512 Gbps
bandwidth. Consider if the distance between the hosts is M metres and the
link speed of the medium is 2 x 109 m/s. If Computer A need to send a one-
kilobyte packet to Computer B. What is the minimum distance M required
such that the propagation delay equals the transmission delay?
Please solve with explainnation
is selective repeat arq the same as selective repeat protocol?
i have a doubt, the sender window size and receiver window size is half of the sequence number. so it is 2 . plz clarify this
in the case of selective repeat.
Why doesn't the sender wait for the acknowledgement for the retransmitted packet..?
Sequence of packet is not maintained then how would it be efficient,?
God bless you
Hi , can someone tell me how the receiver answer by ACK4 before the receiving of frame4 ?!
you are awesome
nice vídeo
but it is not in sequence so will it discard the other frames?
Nope
This is last night before exam and stil half of syllabus is remaining 🥲
Same here
sliding window is required here bcoz how would one achieve flow control without that, the main objective of this whole thing was flow control
crystal cleaer GBN And Selective repeat
A great and super
god bless✨ istg
One doubt..here pack 2 is not acknowledged.
wow so interesting
