basic loader functions in system software

What are the various loader schemes?

 · The loader schemes are: (1 )Absolute loader: The task of an absolute loader is virtually trivial.The loader simply accepts machine language code and places it into main memory specified by the assembler.(2) Relocating loader: The task of relocating loader is to avoid reassembling of of all subroutines when a subroutine is changed and to perform tasks of allocation and linking for programmer.

Linker and Loader are the utility programs that plays a major role in the execution of a program. The Source code of a program passes through compiler, assembler, linker, loader in the respective order, before execution. On the one hand, where the linker intakes the object codes generated by the assembler and combine them to generate the executable module.
