Artificial Intelligence, commonly referred to as AI, is a branch of computer science focused on creating systems that can perform tasks typically requiring human intelligence. These tasks include problem-solving, learning, reasoning, understanding natural language, recognizing patterns, and making decisions. AI systems can be categorized into two main types: narrow AI, which is designed for specific tasks (like voice recognition or image processing), and general AI, which aims to replicate human cognitive abilities across a broad range of activities.

AI utilizes various techniques and algorithms, including Machine Learning (where systems improve through experience), neural networks (inspired by the human brain), and Deep Learning (a subset of Machine Learning that uses large datasets and complex neural networks to learn from them). AI has numerous applications across various fields, including healthcare, finance, transportation, and entertainment, significantly impacting how we live and work.
