Linker

Linker :-Link editors are commonly known as linkers. a computer program that takes one or more objects generated by a compiler and combines them into a single executable program.or, a linker is a program that combines object modules to form an executable program.
Many programming languages allow to write different pieces of code, called modules, separately. This simplifies the programming task because we can break a large program into small, more manageable pieces. So,we need to put all the modules together. This is done by linker.A linker also replaces symbolic addresses with real addresses.
