Define Page Table.
Answer
A Page Table is a massive architectural data structure used to mathematically translate logical virtual addresses into physical RAM frame addresses.
In a Virtual Memory architecture, the Page Table is the absolute critical mathematical lookup matrix maintained by the OS for every single process. It maps a logical Page Number (generated by the CPU) directly to the exact physical Frame Number physically residing in the motherboard's RAM.
