body: <p>Given 2 bytes of data, let say I've 2 bit error.<br>
  <strong>Which one will be the best to use to detect the error?</strong></p>
  
  <p>1D parity bit where one bit is computed for every byte in the data, </p>
  
  <p>or</p>
  
  <p>8 bit checksum computed from every byte in the data, </p>
  
  <p>or</p>
  
  <p>CRC 8 scheme with generator 100000001</p>
