Question

Match List-I with List-II. List-I: A. Compiler, B. Interpreter, C. Linker, D. Loader. List-II: I. Translate one line of the source code at a time and executes the translated instruction. II. A program that is responsible for transferring the executable file from the secondary storage to memory. III. A translation program that translates the program written in a high level language to machine language. IV. A program that combines the object of the program with the object codes of the library and user defined functions, and writes the same in a separate program file with extension usually .exe under Windows OS.

• A. A-IV, B-I, C-III, D-II
• B. A-III, B-I, C-IV, D-II
• C. A-I, B-III, C-IV, D-II
• D. A-III, B-IV, C-I, D-II

Hint:

Compiler translates the whole program, interpreter translates line by line, linker joins object files, and loader loads the program into memory.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
The problem requires matching standard system utility and translation programs with their respective descriptions.

Step 2: Detailed Explanation:
Let us study each of the system programs listed in List-I:

• Compiler (A): A compiler translates high-level source code into low-level machine code all at once before execution. This matches description III.

• Interpreter (B): An interpreter translates high-level code line-by-line, executing each instruction immediately after translating it. This matches description I.

• Linker (C): A linker takes the output of a compiler (object code) and links it with other pre-compiled systems or library files to create a final executable file (such as a ‘.exe‘ file). This matches description IV.

• Loader (D): A loader brings the executable file from secondary storage (hard disk, SSD) and places it into primary memory (RAM) so that the CPU can execute it. This matches description II.

Step 3: Final Answer:
The matching sequence is A-III, B-I, C-IV, D-II, which corresponds to option (B).
