It is called the top as a stack is a LIFO (Last In First Out) structure – the last object added is the first one removed, and is therefore ‘on top’.
Why we use higher order bits of address?
Explanation: The higher order bits indicate the page number which points to one particular entry in the page table. Explanation: If the size is more than the required size then the extra space gets wasted. Explanation: This gives the offset within the page table.
What is lowest order bit?
