The static memory allocation may be through absolute addresses or through PC relative addresses (to allow for relocatable, reentrant, and/or recursive software), but in either case, the compiler or assembler generates a set of addresses that can not change for the life of a program or process.
Virtual memory is a technique in which each process generates addresses as if it had sole access to the entire logical address space of the processor, but in reality memory management hardware remaps the logical addresses into actual physical addresses in physical address space.
Many virtual memory systems also include software for page or segment swapping, shuffling portions of a program to and from a hard disk, to give the software the impression of having much more RAM than is actually installed on the computer.
