title: Disadvantages of Parity Bits
body: <p>What are the disadvantages of parity bits?</p>
  
  <p>I gathered some info but I was hoping someone could expand on them.</p>
  
  <p>• Not capable of finding all errors. Only errors which cause an odd number of bits to flip will be detected. </p>
  
  <p>• No way to know which bit is false. </p>
  
  <p>• Not able to correct the data so the data has to be retransmitted.</p>
  
  <p>• On noisy lines, other detection method such as CRC is used to assure that the sent information is received correctly.</p>
