Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think and learn like humans. It involves the development of algorithms and computer systems capable of performing tasks that typically require human intelligence. These tasks include problem-solving, speech recognition, learning, planning, perception, and language understanding.

Key components of Artificial Intelligence include:

Machine Learning (ML): ML is a subset of AI that focuses on the development of algorithms enabling computers to learn from data. Instead of being explicitly programmed, systems can improve their performance over time through learning from patterns and experiences.

Natural Language Processing (NLP): NLP enables machines to understand, interpret, and generate human language. It involves tasks like language translation, sentiment analysis, and speech recognition.

Computer Vision: Computer vision allows machines to interpret and understand visual information from the world. It involves tasks such as image and video recognition, object detection, and facial recognition.

Robotics: AI is used in robotics to create intelligent machines capable of performing tasks autonomously. This includes applications in manufacturing, healthcare, and various industries.

Expert Systems: These are computer systems designed to emulate the decision-making ability of a human expert in a specific domain. They use rules and knowledge bases to make decisions or provide recommendations.
