A computer system uses $$32$$-bit virtual address, and $$32$$-bit physical address. The physical memory is byte addressable, and the page size is $$4$$ kbytes. It is decided to use two level page tables to translate from virtual address to physical address. Equal number of bits should be used for indexing first level and second level page table, and the size of each page table entry is $$4$$ bytes.

(a) Give a diagram showing how a virtual address would be translated to a physical address.

(b) What is the number of page table entries that can be contained in each page?

(c) How many bits are available for storing protection and other information in each page table entry?

Dynamic linking can cause security concerns because

Which of the following is not a form of memory?

The optimal page replacement algorithm will select the page that.
