- 1100 8. Suppose that a message payload 1001 1100 1010 0011 is transmitted using Internet Checksum (4-bit word). Internet Checksum is 1's compliment (the 1's compliment of a number is it's compliment). What is the value of the checksum transmitted? (A) 0000 (B) 1111 (C) 1101 (E) 000000 1010 9. The binary number 0110110x is transmitted, and the x is an eighth bit that is added to make odd parity, the x is (A) 1(B) 0 10. One way of detecting errors is to transmit data as a block of n rows of k bits per row and add parity bits to each row (bit k+1) and each column (row k+1). The bit in the lower-right corner (k=1, n+1) is a parity bit that checks its row and its column. If k>4, will this scheme detect burst errors of length 4? (A) YES (B) NO (C) Cannot be determined from info 11. In the Go-back-n acknowledgement protocol the timeout interval should be shorter than the maximum time an ack signal is received by the sender. (A) True (B) False 12. In Selective repeat acknowledgement protocol frames can be received out of sequence. (A) True (B) False 13. Go-back-n is a more efficient protocol than Selective repeat because there will be less waste frames in the presence of errors. (A) True (B) False 14. In the simplex stop-and-wait protocol an error may cause multiple retries of the data. (A) True (B) False 15. A noiseless 16khz channel is sampled once every 1ms with an 8 bit sample. What is the data rate? (A) 4Kbps (B) 8kbps (C) 16kpbs (D) none of the above
