Artificial Intelligence (AI) refers to the simulation of human intelligence processes by machines, particularly computer systems. These processes include learning (the acquisition of information and rules for using it), reasoning (the ability to draw logical conclusions), and self-correction. AI systems can perform tasks that typically require human intelligence, such as speech recognition, decision-making, problem-solving, and visual perception. AI can be categorized into two main types: narrow AI, which is designed to perform a specific task (like voice assistants or recommendation systems), and general AI, which would possess the ability to understand, learn, and apply intelligence across a wide range of tasks similar to a human. The field of AI encompasses various sub-disciplines, including machine learning, where algorithms improve through experience, and natural language processing, which enables machines to understand and interact using human language. AI has applications in diverse sectors, such as healthcare, finance, transportation, and entertainment, driving innovation and efficiency across industries.
