Operating Systems

In a computer system that uses paging, the logical address is first translated to a physical address using the page table.
If the page table is stored in main memory, every access to data needs:
- One access to get the page table entry (i.e., frame number), and
- Another access to retrieve the actual data from the calculated physical address.
Hence, each memory access will require two memory operations.
Given that memory access time = 100 ns
Thus, the correct effective access time is 200 ns.
