Error correction works by adding ________ to the transmitted message.
A)decoding
B)clarification
C)error burst
D)redundancy

Question

Quizplus · Accepted Answer

Error correction works by adding redundancy to the transmitted message, which means adding extra bits that allow for detecting and correcting errors in the received message. This process is based on mathematical algorithms that can recover the original data by comparing the transmitted message with the received message and using the extra bits to correct any errors that occurred during transmission. Option A is incorrect because decoding is the process of converting coded information into plain text, which is not directly related to error correction. Option B is incorrect because clarification implies providing more information or explanation, which is not what error correction does. Option C is incorrect because an error burst is a sequence of consecutive errors in a data transmission, which is a specific type of error, but not the solution for correcting errors in general.
