data items given in hexadecimal. So, convert it into binary and then add all these binary codes.if there is a carry then add it. finally do the 1's complement of the result after addition and it will be called 16-bit checksum at sender side. append it to the data items and send it to receiver. if at receiver after adding these codes,if answer is zero then there is no error and checksum will be same at receiver.

Foruzan,Error Detection and Correction: Exercise,Ques:23 Please Explain
23: We need a dataword of at least 11 bits. Find the values of k and n in the Hamming code C(n, k) with dmin :3. Soln: We need to find k = 2m −1 − m ≥ 11. We use trial and error to find the right answer: a. Let m ... 24 −1 − 4 = 11 (acceptable) Comment: The code is C(15, 11) with dmin = 3. How this n=15 came?? please explain

#CN Which protocols provide error correction in data?
TCP UDP IGMP ICMP I think ICMP can’t correct the error in data and rest three protocols can correct data errors!

Error Detection Using CRC
For detecting a single bit error using CRC, it is needed that $x^{i}$ should not be divisible by g(x). So, we make g(x) of at least 2 terms, which renders a single term of e(x) indivisible. But then what is the logic behind keeping MSB as 1. ... any single bit indivisible? For example, $x^{3}+x^{2}$ is guarantees to detect a single bit error at any position. Is it not?
