Problem #2 (a) Calculate the checksum for the following data (consisting of two 16 bit numbers): 1101011011101100 1110010101010100 (10 pts) Note that checksum uses ones-complement operation that involves an end-around carry. (b) Give an example of bit errors in the above data that checksum cannot detect. (5 pts) c) Consider a set of communicating devices (transmitter and receiver) that are using a simple single-bit even parity check for error detection. The transmitter sends the following 8-bit sequence: 11001010. However, owing to channel noise the receiver instead gets the following bits: 10001011. Can the receiver detect the error? Explain why or Why not? (10 pts)
