AI, or Artificial Intelligence, refers to the development of computer systems capable of performing tasks that typically require human intelligence. These tasks include learning from data, recognizing patterns, understanding natural language, solving problems, and making decisions. AI technologies range from simple automation to advanced machine learning and deep learning models, enabling applications such as virtual assistants, image recognition, and predictive analytics. The goal of AI is to create systems that can adapt, improve, and operate autonomously in complex environments.
