this is amazing. wow loved it.... the famous saying here in America is absolutely True .... there's always an Indian guy who makes you understand the IT terms and technology in a simple way lol

Neso academy was the best, is the best and will remain the best educational channel on youtube.

[PrithaMajumder]

Sir, Thank You So Much for This Amazing Lecture 😊
Lecture - 44 Completed ✔

Within half an hour before semester u guyz saved me😊

TQ NESO ACADEMY, for your explanation....super ....happy to have your channel 🥳

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?..

[jahnvipatel]

Great video sir! But what if the redundant data has errors in it?

[rasikarajesh]

Thank you sir it's very helpful 😊👏❤️

[TheIronMan]

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?

[JosefNauyoma]

Thank you Neso Academy for such an informative video, can you give a practical example of where transmission error may occur.

[michaelngatia]

Check difference between multiple bit error and butst error

[bwshiau]

thank you for this video, very helpful!

[carmimweemba]

Thank u so much i've understood now

[ramandeepsingh]

Thank you so much sir for making this video very helpful 🙏

5:00 *what if there is error in redundant bits??*

[sudarshanv]

what if redundant bits are also corrupted?

[kumarAjitesh]

What if redundant bits get altered during transmission? How receiver will get to know what he has received is errorless or contains error?

[vishalyadav]

Sir what happens when redundent bit is currupted during transmission.

[thisisRamK]

how can we ensure the redundant data transmission without error
