What are various linking schemes in system programming?

Answer 1

In system programming, various linking schemes include static linking, dynamic linking, and position-independent code. Static linking involves combining all necessary libraries and modules into a single executable at compile time, resulting in larger binaries but improved execution speed. Dynamic linking loads shared libraries at runtime, allowing for smaller executables and easier updates, but potentially introducing runtime errors if dependencies are missing. Position-independent code enables the same binary to run at different memory addresses, facilitating dynamic linking and shared libraries in modern operating systems.
