Virtual Memory Management (VMM) is code in the kernel which, among other things, helps us to present each process with its own virtual address space. Overcommitment means that processes can request more memory from the kernel than we have available physically and as swap. Please note that this is only allowing us to request more, writing to more than available is not possible. A page is a piece of memory. Paging is the operation of making a copy of a page, for example to a swap device. Swapping is the usage of swap devices, so making copies of pages between physical memory and a swap device. Thrashing is when swapping uses more resources than the other processes on the system. Overview: When is swap used?Swap is used to give processes room, even when the physical RAM of the system is already used up. In a normal system configuration, when a system faces memory pressure, swap is used, and later when the memory pressure disappears and…
