3. Debugging Techniques: ● High level language simulation. ● Low level simulation. ● Task level debugging

4. Compiling Code Definition: The process of translating high-level programming code into machine-readable instructions . Significance: Essential step in software development, enabling the creation of executable programs.

5. The Pre-processor Definition: Software component handling tasks like macro expansion, conditional compilation, and including header files. Contribution: Optimizes code by removing unnecessary elements and improving readability.

6. Compilation: Definition: The stage where the compiler translates source code into assembly code. Purpose: Converts human-readable code into machine-understandable instructions.

7. Assembler: Definition: Converts assembly code into machine code or object code. Role: Translates symbolic instructions into binary code understood by the computer.

8. Linking and Loading Linking: Process of combining multiple object files and resolving external references to create an executable file. Loading: Process of loading the executable file into memory for execution. Linker/Loader: Software components responsible for linking and loading.

9. Writing a Library Definition: Creating a collection of reusable code modules. Purpose: Encapsulating complex functionality for reuse in multiple programs.

10. Downloading: Definition: Transferring compiled code from a development environment to a target device. Methods: Debugger with programming capabilities, bootloaders , flash programmers, etc

11. Debugging Techniques: High-Level Language Simulation : Simulating code execution in a high-level environment to identify logical errors . Low-Level Simulation : Simulating hardware behavior to detect hardware-related issues . Task-Level Debugging : Debugging individual tasks or processes in multi-tasking environments to resolve synchronization and priority conflicts .
