Memory Management and Paging Concepts

Paging allows non-contiguous memory allocation, which helps in efficient use of memory and simplifies the management of memory fragmentation.

Demand paging loads pages into memory only when they are needed, reducing memory usage and improving system responsiveness.

FIFO page replacement removes the oldest page in memory first, while LRU replaces the least recently used page.
