title: 16 bit Int vs 32 bit Int vs 64 bit Int
body: <p>I've been wondering this for a long time since I've never had "formal" education on computer science (I'm in highschool), so please excuse my ignorance on the subject.</p>
  
  <p>On a platform that supports the three types of integers listed in the title, which one's better and why? (I know that every kind of int has a different length in memory, but I'm not sure what that means or how it affects performance or, from a developer's view point, which one has more advantages over the other).</p>
  
  <p>Thank you in advance for your help.</p>
