title: What is a latent error - an example?
body: <p>Quoting an document dealing with taxonomy of threats etc.:</p>
  
  <blockquote>
    <p>An error is detected if its presence is indicated by an error message
    or error signal. Errors that are present but not detected are latent
    errors.</p>
  </blockquote>
  
  <p>Please mind that this is not the same as a dormant fault, which is a defect in the code activated by certain events and producing error when it gets activated.</p>
  
  <p>Also the latent error is an error caused by a fault but not causing a failure. I guess it will be common in multi layer applications, yet I cannot think of any example. But I do not understand one more thing - eventually it has to cause a failure, otherwise it would not be discovered at all, dont you think?</p>
