ALSO CALLED: Array, R A I D Array, Storage Arrays, Arrays, RAID Array, Redundant Array of Inexpensive Disks, R A I D, Redundant Array of Independent Disks, Disk Arrays
DEFINITION: In computers, parity (from the Latin paritas: equal or equivalent) refers to a technique of checking whether data has been lost or written over when it's moved from one place in storage to another or when transmitted between computers.Here's how it works: An additional binary digit, the parity bit, is added to a group of bits that are moved together. This bit is used only for the purpose of identifying  …

RAID DEFINITION (continued): …  whether the bits being moved arrived successfully. Before the bits are sent, they are counted and if the total number of data bits is even, the parity bit is set to one so that the total number of bits transmitted will form an odd number. If the total number of data bits is already an odd number, the parity bit remains or is set to 0. At the receiving end, each group of incoming bits is checked to see if the group totals to an odd number. If the total is even, a transmission error has occurred and either the transmission is retried or the system halts and an error message is sent to the user.The …
