The check is a type of hardware control that involves adding a "1" or a "0" to the end of every 8 bit byte such that the total number of ones in the byte is always either odd or even.
a. byte count
b. parity
c. check digit
d. echo
e. binary

The correct answer to the following question is an option (b) parity.

Explanation:

Because it is a bit that appends to the binary bit and it has the sets of one or either zero by which a total number of the one bits is the odd or the even parity bit.  

Parity bit is a type of bit by which we can check when the data is moved to another place than at that time the data is written over or lost and also we check data at that time when these data is transmitted from one computer to other computers.
