Artificial Intelligence (AI) is a branch of computer science focused on creating machines and software that can perform tasks typically requiring human intelligence. This includes capabilities such as learning, reasoning, problem-solving, understanding natural language, recognizing patterns, and making decisions based on data.

AI can be categorized into two primary types: narrow AI, which is designed for specific tasks (like voice assistants, recommendation systems, and image recognition), and general AI, which aims to perform any intellectual task that a human can do (a goal that remains largely theoretical at this stage).

The technologies and methodologies underpinning AI encompass Machine Learning, where algorithms improve from experience, and Deep Learning, a subset of Machine Learning that utilizes neural networks to process vast amounts of data in complex ways. AI is increasingly integrated into various sectors, enhancing efficiency and innovative capabilities across fields such as healthcare, finance, transportation, and entertainment.
