title: What is a context in Django?
body: <p>I'm a django beginner so I'm trying to understand the concept of context and context processor.</p>
  
  <ul>
  <li>What is a context and why do you use it? </li>
  <li>Is a context a value you need to have available in order to use in a template?</li>
  <li>Is a context and a context processor the same?</li>
  </ul>
