Given a process with an address space requiring 50 KB of data, calculate how many pages of size 16 KB will be needed, and how much internal fragmentation will occur.

Analyze a scenario where a process frequently accesses certain pages and implement a page replacement algorithm to minimize page faults. Discuss how your strategy changes with varying access patterns.
Monitor the access sequence and compare it with your replacement policy.
