Artificial Intelligence (AI) refers to the simulation of human intelligence processes by computer systems. These processes include learning (the acquisition of information and rules for using it), reasoning (the ability to solve problems and make decisions), and self-correction. AI can manifest in various forms, including Machine Learning, natural language processing, computer vision, and robotics.

Machine Learning, a subset of AI, focuses on the development of algorithms that allow computers to learn from and make predictions based on data. Natural language processing enables machines to understand and generate human language, facilitating interactions between people and computers. Computer vision allows AI to interpret and make decisions based on visual data, while robotics involves the design and use of robots that can perform tasks autonomously or semi-autonomously.

AI technologies are integrated into many applications, from virtual assistants like Siri and Alexa to recommendation systems used by platforms such as Netflix and Amazon, enhancing productivity, efficiency, and user experience across various domains. As AI continues to evolve, ethical considerations and the implications of its impact on society are increasingly relevant, prompting discussions about responsible innovation and the future of work.
