I want to know the answer to the following question:
What allowed for a parity bit for error chicking if needed?
All the background I'm provided with is that "Since perforated tape at the time could record eight bits in one position, it also allowed for a parity bit for error checking if desired.:217, 236 § 5 Eight-bit machines (with octets as the native data type) that did not use parity checking typically set the eighth bit to 0.". Is that enough to answer the question?
