title: Understanding Dask-ML
body: <p>I have read through Dask-ML documentation and I have googled around, but have 2 questions I would like some clarity on if anyone could assists:</p>
  
  <ul>
  <li>by saying "using a cluster of computers", does it mean processing is distributed across other people's computers who are connected to the network? If yes, would there be any privacy issues with this?</li>
  <li>would we be able to know how many computers are there in a cluster at any point in time?</li>
  </ul>
  
  <p>Please point me to the right direction or if there are any link that I could read more about this. Thanks in advance. </p>
