parity error
The 74180 is a 9-bit Odd/Even Parity Generator and Checker
A parity generator checks the data to be transmitted and outputs a 0(parity bit) if the number of logic 1's in the data is even, and a logic 0 if the number is odd. So a checker takes the transmitted data and the parity bit and will compare the two, and if they are both of the same logic then the you can conclude that the data was recieved succesfully(i.e no bits were lost during transmission). Parity checker/generator use the exact same devices, but with one comparing instead of generating.

Parity is an error detection method used to ensure integrity of DATA in Transmission or Storage applications. Parity Methods are used in Computing Machines whether it is a Server, Workstation or a Laptop.
It can be calculated via an XOR sum of the bits, yielding 0 for even parity and 1 for odd parity
The parity used by Microsoft is Boolean (true/false, one/zero) logic.
Parity checking is used as a way to ensure data integrity and prevent errors, or detect them in the event they are occuring.
'Put-call parity' is a popular term used among investments. The 'put-call parity' concept is used to describe a relationship between the price of a call and put option.

Digital Logic
RAID-5 provides data redundancy by using parity. Parity is a calculated value used to reconstruct data after a failure. While data is being written to a RAID-5 volume, parity is calculated by doing an exclusive OR (XOR) procedure on the data. The resulting parity is then written to the volume.
There are two types of parity bits.they are even and odd parity.
A parity error always causes the system to hault. On the screen, you see the error message parity error 1 (parity error on the motherboard) or parity error 2 (parity error on an expansion card)
A parity bit, or check bit, is a bit that is added to ensure that the number of bits with the value one in a set of bits is even or odd. Parity bits are used as the simplest form of error detecting code.
