Define linkage editor (linker).

A linkage editor, commonly known as a linker, is a software tool in the programming and software development process responsible for combining multiple object files into a single executable program. The linker resolves references between modules, manages address allocation, and performs various other tasks to create a cohesive and functional executable

Types of Linkers:

1. Static Linker: Combines object files into a single executable at compile time. The resulting executable contains all the code and data needed for execution.
2. Dynamic Linker: Links code from shared libraries or dynamic link libraries (DLLs) at runtime, rather than at compile time. This allows for more flexible and memory-efficient executable files.
