Artificial Intelligence (AI) is a branch of computer science dedicated to creating machines and software that can perform tasks typically requiring human intelligence. These tasks may include problem-solving, reasoning, learning, understanding natural language, recognizing patterns, and making decisions. AI systems can be classified into two broad categories: narrow AI and general AI.

Narrow AI, also known as weak AI, is designed for specific tasks and operates within a limited context, such as facial recognition, voice assistants, or recommendation algorithms. General AI, or strong AI, is a theoretical concept where a machine would possess the ability to understand, learn, and apply intelligence across a wide variety of tasks, similar to that of a human.

AI technologies utilize various techniques, including Machine Learning, natural language processing, and neural networks, to improve their performance over time and adapt to new information. The applications of AI are vast and encompass diverse fields such as healthcare, finance, transportation, and entertainment, significantly impacting how we interact with technology and perform daily tasks.
