For those who are wondering, what if the redundant code(RC)/redundant bits/redundancy check alters in the transmission process? Case 1: RC altered-> The message reaches the receiver, passes through the checking function at receiver's end, generates a validating code which is matched against the altered RC. It wouldn't match obviously. So retransmission can be requested. Case 2: Message Altered-> Both RC and Validating codes are unmatched. Again retransmission is required. Case 3: Both get altered-> Obviously the receiver would generate a validating code for the altered message received and match it against the altered RC from the sender. Both wouldn't match. Again retransmission.
Hello sir, it is a very informative video. Bt i have a doubt. The doubt is, even those redundant bits are transferred over the network. Like other bits, what if the redundant bits also get damaged?..
First of all thanks for making this video sir, but still I have the below doubt: Q: Redundancy bits are also transmitted as signals right, then what if Redundancy bits are corrupted? If it happens then how the receiver can detect the error?
receiver has a copy of the reduntant bits that are sent,so it compares the reduntant bits that it receives with the one that it already have and if both of them matches then it accepts the message otherwiese rejects it.
Actually the frame consists of header ,payload,trailer also called as checksum ..so we place the redundant bits in trailer ...Now the question arises how to calculate redundant bits ?? Simple there're so many algorithms to carryout redundant bits from the actual data so called packet ...when tje frame is transmitted to physical layer ,the physical layer transmits this data to destination in raw bits ...so when it reaches to data link layer it knows what is header ,payload ,and trailer so it Calculates the redundant bits from that payload and checks whether it is equal to actual redundant bits ...if it is same it assumes it as error free if not there will be other operations to carry out based on algorithms
@@Nerd4141 but the question still remains, if the redundant bits get corrupted, how to deal with that, the algorithm you told is correct, but the question is different. because if the redundant bits get corrupted, then there is no point of using this algorithm, so how to find whether redundant bits are corrupted or not.
CHATGPT: If the redundant bits themselves become corrupted, it can lead to uncorrectable errors in the data. This can result in data loss or data corruption, depending on the extent of the error. To mitigate this risk, multiple redundant copies of the data can be stored, so that if one copy becomes corrupted, the others can be used to recover the original data. Additionally, error detection and correction algorithms can be used to detect and correct errors in the data, even if the redundant bits are themselves corrupted.
I think it's work is to detect whether the recieved data has an error or not... Mean if the redundant bits aren't same its mean there is an error in code (transmission error). Further more, it's will be detected and corrected by the reciver checker.
There is copy of redundant bits at receiver end too. If redundant bits don’t match at both ends, receiver generates error. But there is another scenario which could occur, what if redundant bits are matching but the data itself is corrupted, how that things is gonna get rectified or detected?
@@RahulSharma-oc2qd Redundancy bits are generated from algorithm like vrc, lrc if data is corrupted after putting it in algorithm it won't match Redundant bits therefore receiver will detect an error and acknowledge same to the sender. Watch next videos about vrc, lrc checksum you'll understand better.

Neso academy was the best,is the best and will remain the best educational channel on youtube.
Well done brother, best explained 💯💯
Kya baat hai sir mzza aa gya, well explained 💯💯
Within half an hour before semester u guyz saved me😊
Very Helpful and clear
TQ NESO ACADEMY, for your explanation....super ....happy to have your channel 🥳
Amazing explanation skill! Your pleasant voice adds colour to the lecture dude.
Sir, Thank You So Much for This Amazing Lecture 😊
Lecture - 44 Completed ✔
You explain veryyyyyyyyyy well. I loved it a lot.
Great video sir! But what if the redundant data has errors in it?
redundant data never get any error...
For those who are wondering, what if the redundant code(RC)/redundant bits/redundancy check alters in the transmission process?
Case 1: RC altered->
The message reaches the receiver, passes through the checking function at receiver's end, generates a validating code which is matched against the altered RC. It wouldn't match obviously. So retransmission can be requested.
Case 2: Message Altered->
Both RC and Validating codes are unmatched. Again retransmission is required.
Case 3: Both get altered->
Obviously the receiver would generate a validating code for the altered message received and match it against the altered RC from the sender. Both wouldn't match. Again retransmission.

same doubt bro
I love neso academy
Thank you sir it's very helpful 😊👏❤️
Thank you Neso Academy for such an informative video, can you give a practical example of where transmission error may occur.
First of all thanks for making this video sir, but still I have the below doubt:
Q: Redundancy bits are also transmitted as signals right, then what if Redundancy bits are corrupted? If it happens then how the receiver can detect the error?
I have Some doubts. if you find let me know
receiver has a copy of the reduntant bits that are sent,so it compares the reduntant bits that it receives with the one that it already have and if both of them matches then it accepts the message otherwiese rejects it.
@@vishalagrawal7651 How come the receiver already has a copy of the redundant bits?

Thank u so much i've understood now
✌️so good explanation, love it
What if redundant bits get altered during transmission? How receiver will get to know what he has received is errorless or contains error?
This vedios is useful sir
Thank you sir
what if redundant bits are also corrupted?
I think it's work is to detect whether the recieved data has an error or not...
Mean if the redundant bits aren't same its mean there is an error in code (transmission error).
Further more, it's will be detected and corrected by the reciver checker.
can you helped me and make CCNA full course ,a lot of people wanted sir.
thank you very much , good job .
No redundant bits are going through any errors?
Sir what happens when redundent bit is currupted during transmission.
how can we ensure the redundant data transmission without error
Amazing
Check difference between multiple bit error and butst error
Consecutive bit error is bursty error and other side multiple bit error quiet opposite of bursty error
Can any one help me
What is the relation between redundant bit and data..... How receiver finds error or not using redundant bit.
what about multiple error type??
thank you
Tq very much sir
Amazing 👍
Then wt if redundant bits are corrupted?
There is copy of redundant bits at receiver end too. If redundant bits don’t match at both ends, receiver generates error. But there is another scenario which could occur, what if redundant bits are matching but the data itself is corrupted, how that things is gonna get rectified or detected?
Super 👌 👍 sir
Hope you understand my question and Thank you sir.
do you have the presentation ?
❤️TQs. Sir 😢🙏🏻🙏🏻
Sir, what if redundant bits itself got changed?
They don't

Sir our channel has subject experts in every subject, why don't u provide on mathematics
what if redundant bits remain same but data gets corrupted?
Did you get any answers to this?
