title: How are functions encoded/stored in memory?
body: <p>I understand how things like numbers and letters are encoded in binary, and thus can be stored as 0's and 1's.</p>
  
  <p>But how are functions stored in memory? I don't see how they could be stored as 0's and 1's, and I don't see how something could be stored in memory as anything besides 0's and 1's.</p>
