Data Link layer does the parity error checking Thanks, Samaresh
That's called a "parity violation", which indicates a bit error in the byte. That's the whole purpose of parity ... detecting bit errors, although in order to do it, you have to significantly increase the data load by adding an extra bit to every 7 or 8 bits in the end-user's business traffic.
