ITPEC FE Morning April 2021 Question 19
ITPEC FE Morning April 2021 — Question 19 of 80
Linker — resolves cross references and combines multiple object modules into one load module.
What a linker does:
- Takes compiled object modules (.o / .obj files)
- Resolves cross references (external symbols, function calls between modules)
- Produces a single executable load module
Why not others:
- (a) Load a module to main memory — this is a loader
- (b) Monitor execution and record results — this is a tracer / debugger
- (d) Register a program in a library — this is a librarian
Key rule: Compiler → Object module → Linker → Load module → Loader → Execution.
