error in 2D parity example, shouldn't the parity bit for the first column be 0?

[peterlam]

There is an error on 2-D parity example. the first column must be 0.

is the calculation of R correct at 8:10?1010-1001? isn't that supposed to be 0001?

Actually quite liked this one. Those error checkings are pretty cool

Vedio is very good. I really hope that the professor can update the contents of chapters 6-8, although as mentioned on the official website of the book, chapters 7-8 of most computer network courses may only be introductory.

In the no errors 2d parity example I think there's an error, ironically. The parity bit for the first column must be 0.

4:02 The column parity is 00101 --error in column parity
Erroro Correction: 00101 ----result

Awww you seem so nice! Thankyou for the well explained video

You lost me at cyclic redundancy … but I noticed the modulo 2 …. I might get it in abstract algebra terms

Dear Sir, Theorical analysis is not good in Your slide... please reduce the slide number and increase the understandability of theory...
