A system for encoding characters with odd or even bar code patterns.
Parity provides a self-checking feature in bar codes and other data
transmission techniques. Even parity characters have an odd number
of binary ones in their structure. For the purposes of data processing
and data communications, parity does not relate to whether the original
character is odd or even, but how an individual character is made
odd or even with the addition of one more bit (1-0).
A parity bit is added to the binary array to make the sum of all
of the bits always odd or always even for a fundamental check.

PC Standard communications
A communications protocol that handles data transfer on a character-by-character
basis or by either filling a receive buffer or transmitting a buffer

PC BIOS functions. The one exception is that the PC Standard protocol
can buffer data that is received to avoid losing characters if a
program has not checked for data recently.
