Question

Which daemon manages the physical memory by moving process from physical memory to swap space when more physical memory is needed?

1) Sched daemon
2) Swap daemon
3) Init daemon

Answer 1

The Swap daemon is the daemon that manages the physical memory by moving processes from physical memory to swap space when more physical memory is needed. The Swap daemon is responsible for swapping out inactive or less frequently used processes to the swap space, which is a portion of the hard drive used as virtual memory. This frees up physical memory for other processes that require it.

Step-by-step explanation:

The daemon that manages the physical memory by moving process from physical memory to swap space when more physical memory is needed is the Swap daemon. The Swap daemon, often referred to as kswapd in Linux-based systems, is responsible for freeing up physical memory by swapping less-used process pages out to the swap area on the disk. This process helps in ensuring that enough physical memory is available for processes that are actively in use.
