2. Using the CRC polynomial 10101 (= x^4 + x^3 + 1),
a. How many bits a sender append to this information before computing CRC code word?
b. compute the CRC code word for the information word 101101001
c. Check the division performed at the receiver with the cord word of the result of b.
d. If a receiver received a code word, 1011011001010112, does an error in the transmission of information? (Show your work.)
