Artificial intelligence (AI) is a branch of computer science that aims to create machines and software capable of performing tasks that typically require human intelligence. These tasks include problem-solving, understanding natural language, recognizing patterns, learning from experience, and adapting to new information. AI systems can be categorized into two main types: narrow AI, which is designed for specific tasks (like voice assistants or recommendation systems), and general AI, which aims to emulate general human cognitive abilities (a concept that is still largely theoretical). In practical applications, AI techniques include machine learning, where computers learn from and make predictions based on data, and neural networks, which are inspired by the human brain’s structure and functionality. AI technologies have made significant impacts across various sectors, including healthcare, finance, transportation, and entertainment, driving innovations that enhance efficiency and improve decision-making processes.
