Artificial Intelligence (AI) refers to the simulation of human intelligence processes by machines, particularly computer systems. This includes the ability of machines to perform tasks that typically require human intellect, such as understanding natural language, recognizing patterns, solving problems, and making decisions. AI encompasses various technologies and methodologies, including Machine Learning (where systems learn from data), natural language processing (enabling machines to understand and respond to human language), computer vision (allowing computers to interpret visual information), and robotics. As AI continues to evolve, it is being integrated into a diverse range of applications, from virtual assistants and recommendation systems to autonomous vehicles and advanced analytics, fundamentally changing the way we interact with technology and approach problem-solving.
