With this setup, the dynamically linked program doesn’t have to repeatedly access physical memory to access the library. Virtual memory links the same page of physical memory to different programs’ virtual addresses — also known as address space — as different processes are run. More than one application can access a dynamic library at once, because they are not embedded with the executable at compile time. Static libraries are embedded into programs, which lead to duplicates among the multiple programs using them.
