I have come across a question which says If there is a TLB failure in a memory access, the disk must be accessed to load a new page into main memory. The answer is NO, but i dont understand why. Is TLB failure same as TLB miss?

    $\begingroup$ "TLB failure" is not a common term, but presumably "TLB miss" is what was intended. Assuming "TLB failure" did mean "TLB miss", why do you think the disk needs to be accessed when there is a TLB miss? $\endgroup$ – Derek Elkins left SE Apr 2 '18 at 0:22
  • $\begingroup$ The main memory (RAM) will be accessed not the disk, right? @DerekElkins $\endgroup$ – Asfandyar Abbasi Apr 2 '18 at 9:25
  • $\begingroup$ It's hard to know how to correct your misconception without knowing what your current thoughts are. It would help if you edited the question to tell us why you think the answer should be YES. If you can help us understand what specifically you are confused about, we might be in a better position to help you. $\endgroup$ – D.W. Apr 2 '18 at 14:00
  • $\begingroup$ I was confused and thinking that TLB miss and TLB fault are different things, but now I understand that they are the same things. Thanks for helping. $\endgroup$ – Asfandyar Abbasi Apr 2 '18 at 15:16
