title: Meaning of Open hashing and Closed hashing
body: <p>Open Hashing (Separate Chaining):</p>
  
  <blockquote>
    <p>In open hashing, keys are stored in linked lists attached to cells of a hash table.</p>
  </blockquote>
  
  <p>Closed Hashing (Open Addressing):</p>
  
  <blockquote>
    <p>In closed hashing, all keys are stored in the hash table itself without the use of linked lists.</p>
  </blockquote>
  
  <p>I am unable to understand why they are called open, closed and Separate. Can some one explain it?</p>
