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.
The 74180 is a 9-bit Odd/Even Parity Generator and Checker
devices and simulate the circuit using the VHDL codes.
parity error
What are the checker pieces called and what do they represent?
It can be calculated via an XOR sum of the bits, yielding 0 for even parity and 1 for odd parity

Parity bit generator is the error that occures when digital codes are being transferred over channel from one point to other .

3*xor- two input
Exclusive OR gate has a variety of applications. Even parity generator. comparator. encoder etc.
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.

One of its main applications is its use as a parity checker. i am not exactly sure but from what our lecturer stated, this is sometimes to check whether packets of data arrive correctly or not. If someone would like to expand or correct it please do so since i am rather new to these things and would also like a confermation to what our lecturer said thanks.
We check the weather the number of bits at the input are odd or even and assign the parity bit to 1 or 0. And we do the same to check weather the output is the same as the input. Now as the probability of 2 bits going wrong and we may be confident enough just by checking one bit .
There are two types of parity bits.they are even and odd parity.
