Please help me with Prolem 6

Consider the pervious problem, but instead suppose these 10 bytes contain a. the binary representation of the numbers 1 through 10. b. the ASCII representation of the letters B through K (uppercase). c. the ASCII representation of the letters b through k (lowercase). d. Compute the Internet checksum for this data. Consider the 5-bit generator, G = 10011, and suppose that D has the value 1010101010. What is the value of R? Consider the pervious problem, but suppose that D has the value a. 1001010101. b. 0101101010. c. 1010100000. In this problem, we explore some of the properties of the CRC. For the generator G(= 1001) given in Section 6.2.3, answer the following questions. a. Why can it detect any single bit error data D? b. Can the above G detect any odd number of bit in errors? why
