This control entails verifying that the proper number of bits are set to the value 1 in each character received.
A) Echo check
B) Field check
C) Parity check
D) Trailer record

Question

Quizplus · Accepted Answer

The described control is called parity check, which involves adding an additional bit to each character being transmitted to ensure it has an odd or even number of set bits. The receiving end checks if the parity bit matches the expected value based on the number of set bits in the character. If it doesn't match, an error is flagged. Echo check (A) involves transmitting data back to the sender to verify it was received correctly, field check (B) verifies that the data in a field matches a predetermined format or value, and trailer record (D) is a type of record used for data integrity checks or end-of-file markers.
