This degree program should be of interest to and is well suited for those who like working on computers and who ordinarily would also be interested in any of the mathematical sciences (mathematics, computer science, statistics), or any of the natural sciences (biology, chemistry, physics, geological sciences, ...), or any engineering discipline.
Parity bit. A parity bit, or check bit, is a bit added to a string of binary code to ensure that the total number of 1-bits in the string is even or odd. Parity bits are used as the simplest form of error detecting code. There are two variants of parity bits: even parity bit and odd parity bit.
Parity checking uses parity bits to check that data has been transmitted accurately. The parity bit is added to every data unit (typically seven or eight bits) that are transmitted. The parity bit for each unit is set so that all bytes have either an odd number or an even number of set bits. How Parity Checking Works
