title: What is a postback?
body: <p>I'm making my way into web development and have seen the word <strong><em>postback</em></strong> thrown around. Coming from a non-web based background, <strong>what does a new web developer have to know about postbacks? (i.e. what are they and when do they arise?)</strong> </p>
  
  <p>Any more information you'd like to share to help a newbie in the web world be aware of postbacks would be most greatly appreciated.</p>
