Paging
With this approach, a program’s address space is divided up into small 4 KB units called pages - effectively dividing up the program.
The physical memory (the RAM) is divided up into page frames of the same size.
The executing program’s pages are loaded into the next available page frames in physical memory. This helps to make optimum use of the available physical memory without wasting space.
Memory used by programs that have terminated is released and made available to new programs.
