A computer is running on a Windows platform and has nearly exhausted available physical memory for the active processes. In order to avoid exhausting available physical memory, what must the operating system be able to do?
None of the above
Swapping
Paging
Run garbage collector
Paging is a form of memory management that is used in modern operating systems which allows processes to exceed the total physical memory (RAM) available on the system. This methodology allocates blocks of memory as pages; these pages will be moved out of RAM and onto secondary storage when physical memory is being exhausted. Pages can be loaded to physical memory as data is needed from those pages by evicting other pages that are not currently needed from physical memory. On Windows, the location where these pages are held is known as the pagefile. In Unix/Linux, this location may be referred to as the swap file or swap partition.
Garbage collection must be done by the processes. In lower-level languages such as C, this must be done by the programmer. In higher-level languages such as .NET and Java, the virtual runtime environment is responsible for performing garbage collection. If a process fails to perform garbage collection properly and the process exhausts all physical and virtual memory, the operating may chose to forcibly terminate the process and reclaim those resources or the operating system could fail resulting in the Blue Screen of Death.
