  non parity
  
     <storage, communications> An extra bit added to a byte or
     word to reveal errors in storage (in RAM or disk) or
     transmission.  Even (odd) parity means that the parity bit is
     set so that there are an even (odd) number of one bits in the
     word, including the parity bit.  A single parity bit can only
     reveal single bit errors since if an even number of bits are
     wrong then the parity bit will not change.  Moreover, it is
     not possible to tell which bit is wrong, as it is with more
     sophisticated error detection and correction systems.
