What is the name of the process that converts a program written in a high-level language into machine-level instructions that can be run on a computer?

Introduction / Context:
Programmers usually write source code in high-level languages such as C, Java, or Python. Computers, however, execute low-level machine code instructions. A specific process is required to transform human-readable source code into machine-level code that the CPU can run. This question asks for the standard term used to describe this process.

Given Data / Assumptions:

• Source code is written in a high-level programming language.
• The code must be converted into instructions that the computer's processor can execute.
• The options include assembling, compiling, translating, and uploading.
• We assume conventional definitions of compiler and assembler found in programming textbooks.

Concept / Approach:
Compiling is the process of taking high-level language source code and converting it into machine code or intermediate code that the computer can run. A compiler analyses the source code, checks it for errors, and produces an executable or object code. Assembling, on the other hand, converts assembly language (a low-level symbolic representation) into machine code. Translating is a general term that could apply to both compiling and assembling, but it is not the precise technical name for this specific process. Uploading refers to transferring files from one system to another, not converting code. Therefore, compiling is the best and most accurate answer.

Step-by-Step Solution:
Step 1: Identify the starting point: source code written in a high-level language like C or Java. Step 2: Recognise that the destination is machine-level instructions that the processor can execute. Step 3: Recall that a compiler is the tool that performs this conversion, and compiling is the name of the process. Step 4: Distinguish assembling, which converts assembly language, not high-level language, to machine code. Step 5: Understand that uploading deals with moving files across networks or between systems, not changing their internal format. Step 6: Conclude that compiling is the correct term for converting high-level source code into executable machine instructions.

Verification / Alternative check:
Programming manuals and textbooks describe the stages of program development: writing source code, compiling it, and then running the resulting executable. They explain that the compiler translates high-level source code into machine code or bytecode. Assemblers are introduced separately as tools that convert assembly language into machine code. No reputable programming reference defines uploading as code conversion; it is always used in the context of file transfer. This confirms that compiling is the right answer.

Why Other Options Are Wrong:
Assembling: Converts assembly language to machine code, not a high-level language directly. Translating in general: A broad description that lacks the specific technical meaning required by the question. Uploading: Refers to transferring data or files between computers, not to changing source code into executable machine code.

Common Pitfalls:
Students may confuse compiling with assembling because both involve changing code into a lower-level form. The key difference is the starting language: high-level for compiling and assembly language for assembling. Another mistake is to think of any code conversion as translation and choose the generic term translating. While compiling is indeed a form of translation, the precise and widely used term in software development is compiling, and exam questions expect that specific word.

Final Answer:
The process of converting a program written in a high-level language into machine-level instructions that can run on a computer is called Compiling.
