The size of the swap space is decided :

  • A.At the time of operating system installation
  • B.At the time of system start up
  • C.At the time of loading the swapper process
  • D.By the hardware

Answer: A

The size of the swap space is decided at the time of operating system installation.

Swap space is disk space set aside for pages or processes moved out of main memory. On most systems it is a separate disk partition or a preallocated swap file, created and sized when the disk is partitioned during installation of the operating system.

It is not fixed afresh at every start-up or when the swapper is loaded; those simply use the space already configured. The hardware does not decide it either, although the amount of physical memory guides the administrator's choice.
