Part one of term paper
Early transmission codes had a serious problem in that a bit could be lost or gained in transmission because of an electrical or mechanical failure/ If the loss went undetected, the character received on the other end of the lime was incorrect. To Prevent this from happening, a parity check system was developed. Each character is represe ...

... only with characters composed of an uneven number of 1 bits,all characters transmitted will have n even number of 1 bits. The check bit is transmitted to and from the computer along with character code. If a bit is lost (or added) in transmission, the system will detect its loss. An uneven number of 1 bits received in a code string composed of even bits will signal an error. Odd Parity codes add a check bit to code combinations that have an even number of 1 bits. Thus,all characters tr ...
