title: What does it mean by "partial ordering" and "total ordering" in the discussion of Lamport's synchronization Algorithm?
body: <p>What I understand is, partial ordering and total ordering are two sets of rules.</p>
  
  <p>Partial ordering has Three rules:<br>
   (1) if a an b are two events in the same process and a comes before b, then a->b.<br>
   (2) ...<br>
   (3) ...  </p>
  
  <p>What is total ordering then?</p>
  
  <p>Why are the named so?</p>
