title: What is the difference between trap and emulate and binary translation?
body: <p>I understand what trap and emulate is, however I'm struggling to understand what binary translation is and how it differs from trap and emulate. I'm very new to this topic and am trying to understand this introduction from a paper from 2006: </p>
  
  <p><em>"Until recently, the x86 architecture has not permitted classical trap-and-emulate virtualization. Virtual Machine Monitors for x86, such as VMware ® Workstation and Virtual PC, have instead used binary translation of the guest kernel code. However, both Intel and AMD have now introduced architectural extensions to support classical virtualization."</em></p>
  
  <p>I also don't understand what "<em>classical virtualization</em>" is in the context trap and emulate vs binary translation. Any help understanding these terms would be appreciated.</p>
