Loader:
Loader is a system program responsible for setting up an executable program in main memory, making it ready for execution. It plays a crucial role in the execution process by loading the program into memory and preparing it for execution.
Functions of a Loader:
- Allocation of Memory: The loader allocates memory space for the program in the main memory. It ensures that the program is loaded into the correct memory locations without any conflicts.
- Relocation: The loader performs the necessary adjustments to the program's memory addresses, known as relocation, to make sure that the program can run correctly regardless of where it is loaded in memory.
- Linking: In some cases, the loader may also perform linking tasks to connect the program with any external libraries or modules it depends on.
- Resolving Symbolic References: The loader resolves any symbolic references in the program, ensuring that all references to memory locations or external symbols are correctly resolved.
- Initiating Execution: Once the program is loaded into memory and all necessary preparations are made, the loader initiates the execution of the program, handing over control to the operating system.
In the context of the given question, the loader is the system program that is responsible for setting up an executable program in main memory, ready for execution. It is a crucial component of the execution process in a computer system.
