title: Using multithreading to encrypt files simultaneously
body: <blockquote>
  <p>If I have 1 thread encrypting video for 60s</p>
  <p>Can I encrypt 1000 videos</p>
  <p>On 1000 thresds</p>
  <p>In 60s? If so, why/how?</p>
  </blockquote>
  <p>This is from a technical interview. The answer seems to be yes, but I cant say why.</p>
  <p>If you run 1000 threads, then wouldn't CPU processing/power be divided in all 1000? So my answer was no.</p>
  <p>Help?</p>
