Artificial intelligence, or AI, refers to the ability of a computer or machine to perform tasks that would normally require human-like intelligence, such as learning, problem-solving, and decision-making. There are several different types of AI, including narrow or weak AI, which is designed to perform a specific task, and general or strong AI, which is designed to perform a wide range of tasks.

AI can be implemented in a variety of ways, including through machine learning, where a machine is trained to perform a task by being fed large amounts of data, or through the use of rules-based systems, where a machine is programmed to follow a set of specific rules to complete a task. AI has the potential to revolutionize many industries and is already being used in a variety of applications, such as language translation, image and facial recognition, and autonomous vehicles. However, the development and use of AI also raises ethical and social concerns, including issues related to the potential loss of jobs and the potential for misuse or abuse of the technology.
