The result is stored in the parity bit – ‘1’ if odd, ‘0’ if even. When that byte is read from memory, the bits are again counted and the result compared against what was ...

WebAfter the data byte, parity bit is sent. This bit is optional and is used to check for data corruption during transmission. When the data byte is being transmitted, number of high bits are counted from the total 8 bits of the data byte. Now two types of parity checks can be implemented, Odd or Even.
