Logical Address Space (LAS) is divided into equal-sized units known as Pages/Words. The size of these Pages/Words is called Page Size/Word Size.

Let us say the CPU generated 12 LA bits while running a Program. So LAS = 4KB. Now if the Page Size/Word Size decided by the Hardware architecture is 2KB then there will be 2 Pages/Words, The number of Pages can vary based on Page Size/Word Size. That’s why deciding the Optimal Page Size/Word Size is necessary so that there will be no Internal Fragmentation.
