Question

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

Answer 1

The control described in the question is called parity check. It verifies the proper number of bits set to the value 1 in each character received.

Step-by-step explanation:

The control described in the question is called parity check. This is a method used in digital communication to detect errors in data transmission. In parity check, the number of bits set to 1 in each character received is verified to ensure that it matches a predetermined parity bit.

For example, if the predetermined parity is odd, the number of bits set to 1 in the character should be odd as well. If it is even, the number of bits should be even. If the received number of bits does not match the expected parity, it indicates that an error has occurred.
