CNT 3004 - Ch. 10 Homework 1. Which error detection method uses one's complement arithmetic? Checksum 2. Which error detection method consists of just one redundant bit per data unit? SIMPLE PARITY CHECK 3. In cyclic redundancy checking, what is the CRC? THE REMAINDER 4. In cyclic redundancy checking, the divisor is ONE BIT MORE THAN the CRC. 5. A burst error means that two or more bits in the data unit have changed. BURST 6. In FORWARD error correction, the receiver corrects errors without requesting retransmission. 7. In RETRANSMISSION error correction, the receiver asks the sender to send the data again. 8. We can divide coding schemes into two broad categories: BLOCK and CONVOLUTION coding. 9. In modulo-2 arithmetic, ADDITION AND SUBTRACTION give the same results. 10. In modulo-2 arithmetic, we use the XOR operation for both addition and subtraction. 11. In BLOCK coding, we divide our message into blocks, each of k bits, called DATAWORDS 12. We add r redundant bits to each block to make the length
