In which scenario would swap space be particularly useful?

Swap space is a designated area on a hard drive or SSD used as an overflow for RAM when the physical memory is full. This becomes particularly useful when a device needs to handle more simultaneous processes or large tasks than the available RAM can accommodate. In this scenario, if the operating system runs out of RAM, it can move some of the less active data stored in RAM to swap space, freeing up memory for the tasks that need it most urgently. This allows the system to continue functioning efficiently, even under heavy load, avoiding crashes or performance bottlenecks.

While in cases where RAM is sufficient or plentiful, the system may not need to utilize swap space at all. Similarly, situations where the CPU is overloaded with processes or where there's an increase in display resolution do not directly relate to the need for swap space, as these factors pertain more to the processing power and graphical capabilities rather than memory management. Thus, when the demand for processing tasks exceeds the available RAM, swap space plays a crucial role in maintaining system stability and performance.
