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 (using rules to reach approximate or definite conclusions), and self-correction. AI can be categorized into two main types: narrow AI, which is designed to perform a narrow task (like facial recognition or internet searches), and general AI, which has the ability to understand, learn, and apply intelligence across a wide range of tasks similar to a human being.

AI technologies are powered by algorithms, especially those based on neural networks that mimic human brain function, enabling systems to learn from data patterns. Applications of AI span various fields, including robotics, natural language processing, computer vision, and Machine Learning. The ultimate goal of AI research is to create systems that can function autonomously and adaptively, improving their performance over time with minimal human intervention.
