Deep Dive: What is Virtual Memory?
Virtual memory is a memory management technique that creates the illusion that a computer has more RAM than it physically does. It does this by temporarily transferring data from RAM to disk storage (hard drive or SSD), freeing up RAM for active processes.
When your computer runs out of physical RAM, the operating system automatically moves less-used pages of memory to a special area on the hard drive called the page file (Windows) or swap space (Linux/macOS). This process is called paging or swapping.
