Paging + Segmentation |
Paging - The organisation of memory into fixed-sized units, called pages. Segmentation - The splitting of a large program into a number of smaller programs or segments. - Segmentation allows a large program to be executed on a computer with insufficient memory to store the whole program by carving up memory logically rather than physically. |

Virtual Memory |
- Used when sufficient immediate-access store is not available. Part of a disk drive is allocated to be used as if it were main memory. - This is very slow, and the software will use the immediate access store if possible. |
