Linking

  1. Definition: The process of combining different modules and libraries into a single executable program.
  2. Types:
    • Static Linking: Combines all dependencies into one file at compile-time.
    • Dynamic Linking: Links external libraries during runtime.

Loading

  1. Definition: The process of bringing the executable program into memory for execution.
  2. Phases - Loading the Program: Places the code and data in memory. - Relocation: Adjusts memory addresses if needed. - Dynamic Loading: Loads code modules only when needed during execution.

Key Differences:

  • Linking prepares the executable, resolving code dependencies.
  • Loading moves the executable into memory and gets it ready to run.
