Can you explain what Swap is and what equipment implements or manages it?

Swap is a space on a disk or other external storage used by the operating system to extend the available physical memory. When the physical memory (RAM) runs out, the OS can temporarily move inactive data from RAM to swap, freeing up space for active processes.

The hardware that manages swap is primarily the hard drive or SSD, where the swap file or swap partition is located. Swap management is handled by the operating system and its kernel, which decide what data to move and when between RAM and swap.

Thus, swap is not a separate device but a space on the disk used for virtual memory, allowing the system to operate with a memory volume exceeding the physical RAM.
