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.
the simplest checksum algorithm is the so called longitudinal parity check which breaks the data into words with a fixed number n of bits and then computes the exclusive or xor of all those words the result is appended to the message as an extra word
