title: What is Page fault service time?
body: <p>I am reading operating systems and having a doubt regarding page fault service time ?</p>
  
  <p><strong>Average memory access Time = prob. of no page fault (memory access time) 
                       +
   prob. of page fault (Page fault service time)</strong></p>
  
  <p>My doubt is that what does the page fault service time includes ?</p>
  
  <p>According to me, </p>
  
  <p>First address translation is there in TLB or Page table , but when entry is not found in page table, it means page fault occurred . So, i have to fetch from disk and all the entries get updated in the TLB and as well as page table.</p>
  
  <p>Hence, <strong>page Fault service time = TLB time + page table time + page fetch from disk</strong></p>
  
  <p>Plz someone confirm it ?</p>
