What is virtual memory address translation?

Virtual Memory:- 2) A hardware unit called Memory Management Unit (MMU) translates Virtual addresses into physical addresses. 3) If CPU wants data from main memory and it is not present in main memory then MMU causes operating system to bring the data into the Memory from disk.Click to see full answer. Accordingly, what is virtual memory and its use?Virtual memory is a memory management capability of an operating system (OS) that uses hardware and software to allow a computer to compensate for physical memory shortages by temporarily transferring data from random access memory (RAM) to disk storage.Furthermore, what is virtual memory explain the need for virtual memory? It allows us to run more applications on the system than we have enough physical memory to support. Virtual memory is simulated memory that is written to a file on the hard drive. That file is often called page file or swap file. It’s used by operating systems to simulate physical RAM by using hard disk space. Furthermore, what is virtual memory and why it is called virtual? A computer can address more memory than the amount physically installed on the system. This extra memory is actually called virtual memory and it is a section of a hard disk that’s set up to emulate the computer’s RAM. The main visible advantage of this scheme is that programs can be larger than physical memory.What is a page in virtual memory?A page, memory page, or virtual page is a fixed-length contiguous block of virtual memory, described by a single entry in the page table. Similarly, a page frame is the smallest fixed-length contiguous block of physical memory into which memory pages are mapped by the operating system.
