VIRTUAL MEMORY Flashcards
Define Virtual Memory and give an overview of its functionality
Virtual memory allows applications to use more memory than the physically installed one, by combining RAM with disk space.
Paging: It divides memory into pages and swaps them in and out of physical memory as needed.
Page Table: The system uses a page table to map virtual addresses to physical addresses for accurate data access.
Swap Space: When RAM is full, the system uses disk space (swap space) to temporarily hold data, freeing up RAM for other tasks.
State what problem Virtual Memory is designed to alleviate.
problem of limited physical memory by using disk space to extend available memory for running applications.
On a Microsoft Windows based system, state how the default Virtual Memory value is calculated.
the default virtual memory size is typically calculated as 1.5 to 3 times the size of the physical RAM.
