Q
When 2 or more bits in a data unit has been changed during the transmission, the error is called ____________
AA. Random error
BB. Burst error
CC. Inverted error
DD. Double error
Correct Answer:
B. B. Burst error
Explanation:
When a single bit error occurs in a data, it is called single bit error. When more than a single bit of data is corrupted or has error, it is called burst error. If a single bit error occurs, the bit can be simply repaired by inverting it, but in case of a burst error, the sender has to send the frame again.
