title: Difference between binary file and BLOB
body: <p>Watching <a href="https://www.youtube.com/watch?v=tndzLznxq40&amp;t=29s" rel="nofollow noreferrer">this video about how to design Tinder</a>, at 06:50 a point is being made about files vs BLOBS.</p>
  
  <p>I wonder what the difference is between a large binary file and a BLOB (binary large object).</p>
  
  <p>Do they differ by</p>
  
  <ul>
  <li>The method of access</li>
  <li>The method of backup</li>
  <li>Sharding?</li>
  </ul>
  
  <p>What is the origin of difference? They sound quite similar to me.</p>
