Question 4 Explanation:
Linker:
A linker or link editor is a computer utility program that takes one or more object files generated by a compiler and combines them into a single executable file, library file, or another ‘object’ file.
Principles:
1. Resolve external references among separately compiled program units
2. Relocate code and data relative to the beginning of the program.
→ Assembler, Translate assembly language to machine code.
