What does it mean to switch processes in an operating system?
3Question 3.
What is the main benefit of using a translation lookaside buffer (TLB)?
- To store all page table entries
- To reduce memory access times
- To increase the number of pages available

- True
- False
Show hintHide hint
Recall how the operating system handles memory access.
Question 5.
A process requires 1 million page entries, and the page size is 8KB on a 32-bit machine. Calculate the time taken to load a page table into hardware if the load time for one entry is 100 ns.
Show hintHide hint
Convert the total load time to understand how it impacts CPU time during execution.
Question 6.
Explain the implications of a high TLB miss rate on overall system performance and suggest potential solutions.
Show hintHide hint
Consider both hardware improvements and software strategies for addressing TLB effectiveness.
