Natural Language Processing (NLP) is a field that enables computers to understand, interpret, and generate human language. It combines linguistics, computer science, and machine learning to handle tasks like language translation, sentiment analysis, text classification, and question answering. Through NLP, machines can process vast amounts of textual data to find patterns, summarize content, and respond intelligently. This technology powers chatbots, voice assistants, search engines, and more, making human-computer interaction smoother and more natural.
