Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think and learn like humans. It encompasses a broad range of technologies and methodologies aimed at enabling computers to perform tasks typically requiring human intellectual capabilities, such as understanding natural language, recognizing patterns, solving problems, and making decisions. AI can be categorized into several types: narrow AI, which is designed for specific tasks (like voice recognition or image classification), and general AI, which would possess a level of intelligence comparable to a human being across a wide range of activities (though this level of AI has not yet been achieved). AI operates through various techniques, including Machine Learning, where algorithms improve through experience, and neural networks, which mimic the way the human brain processes information. The widespread applications of AI span different fields, including healthcare, finance, transportation, and entertainment, among others, significantly transforming how we interact with technology and streamlining operations in numerous sectors.
