Loader
Loader is a system software that must reside in the main memory under all circumstances for the proper functioning of a computer system. It is responsible for loading programs into the main memory so that they can be executed by the CPU. Here's why the loader is an essential part of the system software:
Program Loading
- The loader is responsible for loading executable programs into the main memory from secondary storage devices such as hard drives or SSDs.
- It ensures that the program is loaded into the correct memory location and is ready to be executed by the CPU.
Memory Management
- The loader plays a crucial role in managing memory resources efficiently by allocating memory space to programs based on their requirements.
- It also ensures that programs do not interfere with each other's memory space, thus preventing memory conflicts.
Error Handling
- The loader performs various checks during the loading process to detect errors such as missing libraries or incompatible file formats.
- It reports any errors to the user or system administrator, allowing them to take appropriate action to resolve the issues.
System Security
- The loader ensures that only authorized programs are loaded into memory, thereby enhancing system security and preventing the execution of malicious software.
In conclusion, the loader is an integral part of system software that must always reside in the main memory to facilitate the loading and execution of programs efficiently and securely.
