Artificial Intelligence (AI) refers to the branch of computer science that focuses on creating systems capable of performing tasks that normally require human intelligence. These tasks include reasoning, problem-solving, understanding language, recognizing patterns, learning from experience, and making decisions. AI can be categorized into two main types: narrow AI, which is designed for specific tasks (like virtual assistants or recommendation systems), and general AI, which aims to replicate human cognitive functions across a wide range of activities. AI technologies leverage Machine Learning, Deep Learning, natural language processing, and robotics to enable machines to learn from data, adapt to new inputs, and perform complex tasks efficiently and accurately. AI applications are prevalent in various fields, including healthcare, finance, transportation, and entertainment, transforming industries by increasing efficiency and optimizing processes.
