Virtual address: The pointer for a memory location allowed by the operating system to the process for using it is called the virtual address. It refers to a location in the primary memory that can be used by the process freely of other processes. It can be possible that the virtual address is the same as the physical address. Physical memory space and the virtual memory space are independent of each other. Virtual Memory Space is not limited by the size of the physical memory space but is limited by the size of virtual addresses. If the virtual memory address and the physical Memory address are different then the mapping is done with the help of the Memory Management Unit (MMU). `JEET answered Oct 25, 2019 • edited Oct 25, 2019 by `JEET `JEET comment Share Follow See all 0 reply Please log in or register to add a comment.
