A compiler generally creates each object file with the program addresses starting at zero. But if a program is created from multiple object files, these will overlap. What we have seen in this section is the `relocation` process. This process assigns load addresses to the various parts of the program, adjusting the code and data in the program to reflect the assigned addresses.
