The following illustration explains the process of virtual addressing when a program is loaded into memory. For detailed explanation, refer to "Understanding Memory: Virtual Addressing".

Executable program image file loads into memory.
Logical memory address range of the application is divided into fixed-size chunks caled pages.
Page mapping in Virtual Memory is dynamic.
Frequently referenced logical addresses tend to reside in physical memory.
Infrequently referenced pages are relegated to paging files on secondary disk storage.
