Artificial Intelligence (AI) is the field of computer science that aims to create machines capable of mimicking human intelligence. These systems can perform cognitive functions such as learning, reasoning, problem-solving, perception, and language understanding. The concept of AI has evolved significantly over the decades, encompassing various techniques and approaches that allow machines to interpret data, adapt to new information, and make decisions.

At its core, AI involves programming computers to process data and make decisions based on algorithms that simulate human thinking. These algorithms allow machines to analyze large datasets, identify patterns, and take actions that would typically require human cognition. The capabilities of AI systems vary widely depending on their design, purpose, and level of sophistication. As a result, AI is often classified into three primary categories: Narrow AI, General AI, and Super AI.
