Your Answer for Question 1:
A virtual address is an address that corresponds to the representative location of a page of memory in a per program virtual space. Physical adrresses represent actual locations in memory. VA's must be converted to PA's to access and locate data. To convert a VA to a PA, you look in the program's page table which can be found starting at the page table register.

Your Answer for Question 2:
With fixed-sized chunks, the VM system does not need to store an offset for each block, and doesn't have to do bounds checking. Bigger chunks increase performance with spatial locality, amortize the high page fault time and have less overhead for page tables. Small chunks can decrease internal fragmentation which can save memory.
