Question

State whether following statement is TRUE OR FALSE :.

If TLB hit occur then  page fault will never be occur.  

Explain your Answer.

Answer 1

The statement is false

Translation Lookaside Buffer (TLB) is used to store the recent translations of virtual address to physical addresses for faster retrieval. Once we get the physical address, we go to the memory location to get the page. If we cannot find a page at that location, it is called page fault.

So, TLB Hit has no relation with Page fault and neither TLB Miss has any relation with page fault.
