swapmemory
Swap memory, or swap space, is a portion of a computer's non-volatile storage that an operating system can use as an extension of RAM for virtual memory. When physical memory becomes scarce, the OS moves less frequently used memory pages from main RAM to swap to free up RAM for active processes. This helps prevent memory exhaustion and allows larger workloads, but it comes at the cost of slower access times.
Swap can be implemented as a dedicated partition or as a swap file contained within a filesystem.
Performance considerations: Accessing data in swap is substantially slower than RAM, so heavy swapping can degrade
Management and monitoring: Administrators can enable or disable swap, create partitions or files, and adjust parameters
