Artificial Intelligence (AI) refers to the simulation of human intelligence processes by machines, particularly computer systems. This encompasses various capabilities such as learning, reasoning, problem-solving, perception, and natural language understanding. AI technologies are classified into two main categories: narrow AI, which is designed to perform specific tasks (like facial recognition or voice assistants), and general AI, which aims to execute any intellectual task that a human can do. The development of AI involves various fields, including Machine Learning, which enables systems to learn from data and improve over time, and neural networks, which are modeled after the human brain to recognize patterns and make decisions. AI has applications across many sectors, including healthcare, finance, transportation, and entertainment, and continues to evolve rapidly, raising both opportunities and ethical considerations in its use.
