WebLinkers and loaders now divided up the work, with linkers doing part of the address binding, assigning relative addresses within each program, and the loader doing a final relocation step to assign actual addresses. As systems became more complex, they called upon linkers to do more and more complex name management and address binding. Relocation is the process of assigning load addresses for position-dependent code and data of a program and adjusting the code and data to reflect the assigned addresses. Prior to the advent of multiprocess systems, and still in many embedded systems, the addresses for objects were absolute starting at a … See more Object files are segmented into various memory segment types.
