title: Dynamic vs Static instruction count
body: <p>What is the difference between dynamic and static instruction count? </p>
  
  <blockquote>
    <p>a. Derive an expression to calculate the user CPU time as a function
    of following          parameters: the dynamic instruction count (N),
    clock cycle per instruction (CPI) and clock frequency (f)</p>
    
    <p>b. Explain the reason for choosing ‘dynamic’ instruction count as a parameter in Question 3a
     instead of ‘static’ instruction count</p>
