body: <p>In cloud computing, what do people mean by...</p>
  
  <ul>
  <li>nodes?, and</li>
  <li>traversal of nodes?</li>
  </ul>
  
  <p>Is it just two different computers which are communicating, or two different entities, or a server and a client?</p>
  
  <p>Please explain. I tried googling this topic but I only get results about nodes in data structures.</p>
