Virtual Memory is a system that allows a computer to extend its usable memory beyond the physical RAM by using a portion of the hard drive (or SSD) as temporary memory.
It provides:
- The illusion of more memory than physically exists.
- Memory isolation between programs for safety.
- Efficient multitasking.
Additional Notes:
- Virtual memory allows larger applications to run without needing more physical RAM.
- Performance may slow when disk is used heavily (known as paging or swapping).
