Which of the following can help to detect transmission errors by appending specially calculated bits into each segment of data?

Correct option is A

A redundancy check helps detect transmission errors by adding extra bits, known as redundant bits, to the data. These bits are calculated in such a way that any error in transmission can be detected at the receiving end. This method ensures the integrity of the transmitted data by comparing the received data with the redundancy bits.
Important Key Points:
1. Redundancy Check: It adds extra bits to data segments for error detection. These bits are used to identify any data corruption during transmission.
2. Error Detection: By appending calculated bits, redundancy checks ensure that the receiver can detect whether any bits have been altered during transmission.
Knowledge Booster:
· Integrity Check: Ensures that the data remains unaltered during transmission but doesn't necessarily involve appending bits like redundancy checks do.
· Accuracy Check: Generally, ensures that the data is correct, but it does not involve adding extra bits like redundancy or parity checks.
· Completeness Check: Confirms that all required data has been transmitted, but it doesn't focus on error detection through additional bits.
