Which term describes a branch of artificial intelligence that converts human language into data usable by computer systems?

• A. Robotic automation
• B. Computer vision
• C. Machine learning
• D. Natural language processing (NLP)

Answer: (D)

Natural language processing focuses on enabling computers to understand human language and convert it into data they can use. It covers tasks that turn spoken or written language into machine-readable representations—like breaking down sentences, grasping meaning, identifying entities, and enabling actions such as chat responses, voice assistants, or translation. This is exactly what happens when language is transformed into structured data that a computer system can analyze and act upon.

Other terms describe different areas: robotic automation focuses on automating physical or business processes with robots; computer vision deals with interpreting visual data from images or video; machine learning is the broad set of algorithms that learn from data, not language specifically. NLP is the field that handles turning language into data a computer can process.
