Description

Inverted page tables are one of the page table additions. Inverted page tables take up a fraction of the area of traditional page tables. The input for this technique is a single page table, with each item representing one of the operating system's actual pages. Most modern operating systems use memory shifting mechanisms when there is more supplementary memory than actual master memory. The operating system uses memory swapping to set page tables by borrowing memory from secondary memory. When a job's main memory is depleted, the operating system moves to secondary memory to fill the void (or disk). The switch space refers to the disk space that has been borrowed. The application (or process) or its code have no control over memory swapping. The entire procedure is controlled by the operating system that runs the software. References: Arpaci-Dusseau, R.
