Answer» Swap space is like pagefile in windows. Swap space is virtual memory where disk reserved for swap will behave like actual RAM. In Swap space, Some amount of physical disk to hold some transaction or data temporarily. Ideally, this data should be residing in RAM or memory but due to a situation where memory is under pressure, the system moves some transaction or data into swap space. RAM is always costlier than disk space and disk performance is INCREASING day by day. Physical Memory need PROPER management for cost-effectiveness and swap SPACES help in USING the disk as a physical memory or temporary and least used data. The system will consider this as a part of memory only. Swapping of memory to and from physical storage is managed by systems memory management. By default, this is an auto driven process and does not REQUIRE any manual intervention. For more accurate memory management We also have the tools to manage swap space as per our requirements |
