4 a. Network performance is poor if there are errors in received data. Parity checking is a simple method of detecting errors. Describe one problem that might arise when using even parity checking. Use an example to illustrate your answer. [3 marks] Among the popular method for error detection is using Internet checksum. If the Internet checksum method is adopted, what message will be sent if data is 5AD3 EE35? If the message received is 59D3 EF45 B6F6, will the message be accepted? [6 marks] c. A bit stream 1011101111 is transmitted using the standard CRC method. With predetermine pattern, P, accepted by both A & B stations is 101101, determine the by using modulo 2 arithmetic method, determine the Frame Check Sequences (FCS) and the message that should be transmitted from A to B.
