03 (a) Provide an example showing that two dimensional parity checks can detect and correct 1 bit error. it cannot correct a two bit error, though detect it. (b) Compute the Internet checksum of the following: 00000000 00000001 00000010 00000011 00000100 00000101 00000110 00000111 00001000 00001001 (c) What would be the received message if CRC8 polynomial x8 x2+x 1 was used and the original message was 1011 0010 0100 1011
