Explanation / Answer
Answer:
The Answer is option:c (all the above)
For E.g. If the data is 7-bit data i.e 0000000, and the parity bit is 1 (indicates odd parity) the 8-bit data is 00000001. If the data received by the receiver is 00000001, then the data is error free. (Which satisfies the option: a)
If the data is 7-bit data i.e 0000000, and the parity bit is 1 (indicates odd parity) the 8-bit data is 00000001. If the data received by the receiver is 11111111, then the data has odd number of errors (seven 0's have been changed to seven 1's, which satisfies option: b)
