title: Does the frequency of machine effect execution time of my code?
body: <p>I have written code which performs a specific task; now when I will run on different machine(having different frequency) will it take different time?</p>
  
  <p><strong>Ouestion</strong></p>
  
  <p>If my code has one <code>printf</code> function, then will its required number of machine cycles be fixed for all machines, or will it depend on the system?</p>
  
  <p>My system frequency is 2.0GHz, what does it mean?</p>
