title: Where is Heap and Stack on Physical Memory?
body: <p>I read by some googling about Heap &amp; Stack, but most answer says just its concept description, differences. </p>
  
  <p>I am curious other things.</p>
  
  <ol>
  <li><p>as title says, Where is Heap and Stack on Physical Memory? </p></li>
  <li><p>How is their size? For example, I use 12 giga byte memory at my desktop PC, then how much is Heap? and how much is Stack size?</p></li>
  <li><p>Who made these 2 different type concept?</p></li>
  <li><p>Can I manipulate Heap &amp; Stack's allocation? if they take 50% of memory each, (if Heap take 6 giga byte memory, Stack take 6 giga byte too in my case), can I resize them?</p></li>
  </ol>
