Q. Why we need linker?

 The linker:

  • Joins assembled module in one executable program,
  • Produces an .EXE module and initializes with special instructions to facilitate its subsequent loading for execution.

The very last step is to load the program for execution. Since the loader knows where the program is heading to load in memory, it's now able to resolve any remaining address still left incomplete in header. Loader drops the header as well as creates a program segment prefix (PSP) instantly before program is loaded in memory.
