Question

The programme that is used to store the machine language programme into the memory of the computer, is called :

• A. Compiler
• B. Loader
• C. Interpreter
• D. Assembler

Answer 1

Answer:

B. Loader

• A Loader is a system program that loads machine language programs into the computer's memory for execution. When a program is compiled or assembled, it exists as a file on secondary storage (like a hard disk). The loader's primary function is to:

  1. Load the program: Transfer the machine language program from secondary storage into the main memory (RAM)

  2. Allocate memory: Assign appropriate memory locations for the program

  3. Relocate addresses: Adjust memory addresses if needed to fit the program into available memory space

  4. Link libraries: Connect the program with necessary library functions

  5. Initialize execution: Prepare the program for execution by setting up the program counter and other registers

• Why other options are incorrect:

  • Compiler: Translates high-level language programs (like C, Java) into machine language or intermediate code, but does not load programs into memory

  • Interpreter: Executes high-level language programs line by line without producing a complete machine language program

  • Assembler: Converts assembly language programs into machine language, but does not load them into memory

• The loader is an essential component of the operating system that bridges the gap between a stored program and its execution by placing it in the appropriate memory locations.
