A computer program that converts an entire program into machine language is called an:

Correct option is C

Correct Answer: (c) Compiler
Explanation:
· A compiler is a computer program that converts an entire high-level programming language code into machine language (binary code) in one go, before execution. This allows the program to run faster since the translation happens before execution. Examples include GCC for C/C++ and the Java Compiler for Java programs.
Other Options:
· Interpreter: An interpreter translates high-level code into machine language line by line during execution, making it slower than a compiler.
· Simulator: A simulator mimics the behavior of a system but does not perform code translation.
· Converter: This is a generic term and does not specifically refer to the translation of code into machine language.
