Artificial Intelligence (AI) is a branch of computer science focused on creating systems capable of performing tasks that typically require human intelligence. These tasks include reasoning, learning, problem-solving, understanding natural language, recognizing patterns, and making decisions. AI technologies can be divided into two main categories: narrow AI, which is specialized in a specific task (like voice assistants, recommendation systems, and image recognition), and general AI, which aims to replicate human cognitive abilities across a wide range of tasks. The underlying technologies of AI involve Machine Learning, where algorithms improve through experience, and Deep Learning, which utilizes neural networks to process data. AI has applications across various fields, including healthcare, finance, transportation, and entertainment, transforming how we work, communicate, and interact with the world.
