title: Why my comupter is showing two different architectures on excuting two different commands?
body: <p>I am using Intel chip set motherboard with i3 Processor. I have installed ubuntu-16.04.2-desktop-amd64.iso since it is only readily available (I believe, there is no specific build called x86_64).</p>
  
  <p>I executed <strong>lscpu</strong> and <strong>dpkg --print-architecture</strong> in terminal. First one is giving architecture as <strong>x86_64</strong> and later is showing <strong>amd64</strong>. </p>
  
  <p>I guess <strong>amd64</strong> and <strong>x86_64</strong> are internal architecture of cpu or is it the architecture of <strong>OS</strong>?.</p>
