Parity Flag & Carry Flag. b. Parity Flag … Web18 Mar 2024 · Solution: The ASCII code of the character ‘A’ is 01000001. Now we need to generate both the even parity and odd parity bit for the character ‘A’. The ASCII code of ‘A’ already has two 1s, that is, even. So the even parity bit will be ‘0’ so that the total number of 1s, including the parity bit, will be even. Peven = 0.
