Address binding of instructions and data to memory addresses can occur at three differ stages as follows:

Compile time: When memory location identified a priori, absolute code can be created; should recompile code but starting location changes.
Load time: It should generate relocatable code when memory location is not identified at compile time.
Execution time: Binding delayed till run time if the process can be moved throughout its execution from one memory segment to other. Required hardware support for address maps (for example: base and limit registers).
