All good for me. By 1969, the debate over virtual memory for commercial computers was over;[3] an IBM research team led by David Sayre showed that their virtual memory overlay system consistently worked better than In this mode every virtual address corresponds to the same real address. Indeed, the OS has a special facility for "fast fixing" these short-term fixed data buffers (fixing which is performed without resorting to a time-consuming Supervisor Call instruction). https://en.wikipedia.org/wiki/Virtual_memory

Microsoft recommends that you set virtual memory to be no less than 1.5 times and no more than 3 times the amount of RAM on your computer. official site Main storage as seen by a process or task appears as a contiguous address space or collection of contiguous segments.

Page tables Page tables are used to translate the virtual addresses seen by the application into physical addresses used by the hardware to process instructions; such hardware that handles this specific Virtual Memory In Operating System Reply Gavin February 10, 2015 at 11:55 am I've never actually done that tbh, Jay.
