Tweet Memory Virtualisation Basics When an operating system is installed directly onto the physical hardware in a non-virtualised environment, the operating system has direct access to the memory installed in the system and simple memory requests, or pages always have a 1:1 mapping to the physical RAM, meaning that if 4GB of RAM is installed, [...]
