Memory Management Technique that divides both physical and virtual memory into fixed-size blocks called pages (typically 4KB). Eliminates External Fragmentation.
The Memory Management Unit (MMU) translates virtual to physical addresses on every memory access, cached by the Translation Lookaside Buffer (TLB).
Advantages over Partitioned Allocation:
- No External Fragmentation
- Process memory does not need to be contiguous in physical memory
- Enables Virtual Address spaces larger than physical Random Access Memory (RAM) (swap)
- Memory protection per page (read/write/execute flags)
Used by all modern Operating System (OS)
