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.
What does the parity bit do in RAID? The use of parity bits is a common method of detecting errors in data transmission and storage. Before looking at the use of parity bits in RAID, let's look more generally at their use as a method of error detection. In data transmission, if data is sent from one device to another without any form of error correcting mechanism, the receiving device must assume the data is correct.
