What Is Linker ?

A program that takes as input the object

files of one or more separately compiled

program modules, and links them together

into a complete executable program,

resolving reference from one module to

another.

Types Of Linkers:

I. Linking loader: This linker performs all the linking and relocation operations and load the linked program directly into the main memory.

II. Linkage editor: This linker produces a linked version of the program called as a load module or an executable image.

III. Dynamic linker: This scheme postpone the linking function until execution time. Any subroutine is loaded and linked to the rest of program when it is first called.
