In this video, we explore Memory Management — how an operating system manages main memory, maps addresses, and ensures efficient and safe use of RAM. This lesson covers both the fundamentals and advanced concepts used in modern systems.

✨ Topics covered:
Logical vs Physical Address Space
Base and Limit Registers
Memory Management Unit (MMU)
Swapping & Backing Store
Paging and Page Tables
Free Frames and Non-contiguous Memory Allocation
Segmentation (Code, Data, Stack)
Valid–Invalid Bit and its role
Page Faults and Page Fault Handling
Page Replacement and why it is needed
Page Replacement Algorithms:
• FIFO (First-In-First-Out)
• Optimal
• LRU (Least Recently Used)
Belady’s Anomaly
Comparison of FIFO, Optimal, and LRU
Learn how operating systems handle memory efficiently, prevent illegal access, and optimize performance using different memory management techniques.
