If the frame to be transmitted is 1101011011 and the CRC polynomial to be used for generating checksum is x^4 + x + 1, than what is the transmitted frame?

  • A. 11010110111110
  • B. 11010110111101
  • C. 11010110111110
  • D. 11010110111001

Answer: A. 11010110111110

Explanation: Message 1101011011. Poly 10011. Append 4 zeros: 11010110110000. Divide by 10011. Remainder is 1110. Transmitted frame: 11010110111110.
