What is the size of the memory according to the size of the address?

I'm having some difficulty answering two questions based on the following information:

  • Supports virtual memory hardware;
  • Works with 1KB pages;
  • Works with 24-bit virtual addresses;
  • Works with 16-bit physical addresses;
  • Has only 1 page table for mapping the entire address space virtual;

What is the maximum amount of physical memory that can be installed?

What is the maximum amount of virtual memory that can be accessed?

It's pure math.

  

What is the maximum amount of physical memory that can be installed?

2 (the amount that a 1 can have) raised to 16 (the amount of bits available) gives 65536, or 64KB.

  

What is the maximum amount of virtual memory that can be accessed?

Here is 2 to 24 which gives 16MB.

Other information is irrelevant to these questions.
