Question and answer is a methodical exchange in which a question is posed and a response is provided. It is used across many domains to convey information, verify facts, or assess knowledge. In education, teachers use question-and-answer formats to prompt recall, comprehension, and discussion. In media and publishing, Q&A columns or interviews present expert or audience-facing perspectives in a question-driven narrative. In customer service and knowledge bases, FAQs and help desks organize common inquiries and provide standardized responses.

In computing and information retrieval, question answering refers to systems designed to interpret a user’s query and return a relevant answer, often from a structured database or large text corpora. Early examples appeared in reference works and educational software; modern Q&A systems employ natural language processing and machine learning to handle open-ended queries and to generate or retrieve concise explanations.

Questions vary in type, from fact-based and yes/no queries to open-ended or procedural requests. Answers may be concise or detailed, include steps, and may cite sources. The quality of Q&A depends on the clarity of the question, the reliability of the source, and the system’s ability to interpret context and ambiguity.

Question-and-answer formats aim to support learning, decision making, and rapid information access, but they can mislead if questions are vague or if answers are outdated or biased. Effective use emphasizes precise wording, source evaluation, and appropriate scope.
