Artificial intelligence (AI) is a branch of computer science that focuses on creating systems capable of performing tasks that typically require human intelligence. These systems can analyze data, learn from it, reason through information, and make decisions based on their findings. AI encompasses a wide range of technologies and methodologies, including machine learning (ML), natural language processing (NLP), robotics, and computer vision, among others.

AI operates on the basis of algorithms that enable computers to process and interpret large volumes of data, recognizing patterns and making predictions or decisions without explicit instructions. Applications of AI are extensive and can be found in various sectors, such as healthcare for diagnosing diseases, finance for detecting fraudulent transactions, customer service through the use of chatbots, and autonomous vehicles navigating complex environments.

The development of AI raises important ethical considerations, particularly regarding privacy, bias in algorithmic decision-making, and the potential for job displacement. As technology advances, the role and impact of AI in society continue to evolve, making it a subject of significant interest and discussion in both the technology community and the general public.
