often referred to as just VMS, is a multi-user, multiprocessing and virtual memory-based operating system. It is designed to support time-sharing, batch...

low-level dynamic memory allocation code in the operating system, when mapping virtual memory to physical memory. A virtual memory subsystem that lacks...

addresses (actual locations in hardware memory) were the same. However, with the introduction of virtual memory most application programs do not deal directly...

for example, virtual memory can provide a program with the illusion of nearly unlimited memory that exceeds the computer's actual memory. Operating systems...
