  <blockquote>
    <p>NVIDIA PerfKit SDK allows graphics developers access to low-level NVIDIA GPU<br>
    <strong><em>performance counters</em></strong> and NVIDIA <strong><em>driver counters</em></strong>. </p>
  </blockquote>
  
  <p>I want to understand the meaning of these counters? Are they some kind of hardware or software? What do they do?</p>
  
  <p>How they are helpful to me? Please give examples of making use of them.</p>
