Last updated August 8, 2026
Definition
Virtual memory lets the OS give processes a large address space by storing inactive pages on disk when physical RAM is full, swapping them back when needed.
Real-World Example
Opening many apps may cause disk thrashing as the OS uses virtual memory to page data in and out of RAM.
