Artificial intelligence refers to the development of computer systems that can perform tasks that would normally require human intelligence. This involves the ability to learn, reason, understand natural language, and solve problems. AI algorithms are designed to analyze vast amounts of data and make predictions or decisions based on the patterns and information they find. AI is used in various fields, including healthcare, finance, gaming, transportation, and customer service. It has the potential to significantly impact society by optimizing processes, improving efficiency, and creating new opportunities. However, it also raises ethical and societal concerns that need to be addressed as AI continues to advance.
