Artificial Intelligence (AI) refers to the field of computer science that focuses on creating systems and machines capable of performing tasks that would typically require human intelligence. These tasks include reasoning, problem-solving, understanding natural language, learning from experience, and perception. AI technologies employ a variety of approaches, including Machine Learning, where algorithms improve through experience and data, and Deep Learning, which uses neural networks to analyze vast amounts of information.

AI can be categorized into two main types: narrow AI, which is designed for specific tasks (like voice assistants or recommendation systems), and general AI, which aims to replicate human cognitive functions across a wide range of activities. While narrow AI is widely used in various applications today, general AI remains largely theoretical and is a topic of ongoing research.

AI has numerous applications across industries, ranging from healthcare and finance to entertainment and transportation, and continues to evolve as technology advances, presenting both opportunities and challenges in various societal contexts.
