Is it possible to use OS without virtual memory support on the hardware with virtual memory support? In other words, is it necessarily required for OS to support virtual memory if hardware uses virtual memory system? For example, as far as I know, MS-DOS does not support virtual memory, however it runs on x86 processors with virtual memory support

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.

Virtual Memory References: Abraham Silberschatz, Greg Gagne, and Peter Baer Galvin, "Operating System Concepts, Ninth Edition ", Chapter 9 9.1 Background. Preceding sections talked about how to avoid memory fragmentation by breaking process memory requirements down into smaller bites ( pages ), and storing the pages non-contiguously in memory.

Feb 10, 2017 · Virtual Memory in Operating System Virtual Memory is a storage allocation scheme in which secondary memory can be addressed as though it were part of main memory. The addresses a program may use to reference memory are distinguished from the addresses the memory system uses to identify physical storage sites, and program generated addresses are ...3/5

Virtual memory, on the other hand, allows the program to specify any address and the operating system and hardware do the hard work of translating to a physical address. The TLB The Translation Lookaside Buffer (or TLB for short) is the main component of the processor responsible for virtual-memory.

May 15, 2017 · The translation between the 32-bit virtual memory address that is used by the code that is running in a process and the 36-bit RAM address is handled automatically and transparently by the computer hardware according to translation tables that are maintained by the operating system. Any virtual memory page (32-bit address) can be associated with any physical RAM page (36-bit address).Windows 2000 Advanced Server: 8 GB

The additional capability of providing virtual address spaces added another level of security and reliability, thus making virtual memory even more attractive to the market place. Most modern operating systems that support virtual memory also run each process in its own dedicated address space. Each program thus appears to have sole access to ...
