Loader
The loader is an important component of an operating system that performs several essential functions related to the execution of programs. It is responsible for preparing a program for execution by allocating memory, resolving symbolic references, and loading the machine instructions and data into memory.
Functions of the Loader:
1. Allocate memory for the programs:
The loader is responsible for allocating memory space to the programs that are being loaded. It determines the amount of memory required by the program and reserves that space in the computer's memory. This ensures that the program has enough memory to execute its instructions and store its data.
2. Resolve symbolic references:
During the compilation process, programs often make use of symbols that represent memory addresses or other variables. These symbols need to be resolved to their actual memory locations before the program can be executed. The loader performs this task by linking the symbolic references to the appropriate memory addresses.
3. Address dependent locations:
The loader also handles the task of addressing dependent locations, such as address constants, to correspond to the allocated memory space. It ensures that the program's instructions and data are correctly placed in memory and that all references are updated to reflect the allocated space.
4. Physically place machine instructions and data:
Once the memory has been allocated and the symbolic references have been resolved, the loader physically places the machine instructions and data into memory. It reads the executable file and copies the instructions and data to their respective memory locations. This process prepares the program for execution by making its instructions and data accessible to the processor.
Conclusion:
In summary, the loader performs several important functions including memory allocation, symbolic reference resolution, addressing dependent locations, and physically placing machine instructions and data into memory. These functions are essential for preparing a program for execution and ensuring that it runs correctly within the computer's memory system.
