Computer Awareness Artificial Intelligence Competitive Exams

Artificial Intelligence, commonly called AI, is a branch of computer science that enables machines to perform tasks that normally require human intelligence. These tasks include learning, reasoning, problem solving, decision making, speech recognition, image recognition, language understanding, and automation. AI is widely used in education, healthcare, banking, transport, agriculture, business, security, and everyday digital applications.

What is Artificial Intelligence?

Artificial Intelligence is the ability of a computer system or machine to perform tasks that usually need human intelligence. An AI system can analyze data, identify patterns, make predictions, understand language, recognize images, and improve its performance using experience.

For example, when a mobile phone suggests words while typing, a map app finds the best route, a shopping website recommends products, or a chatbot answers questions, artificial intelligence may be working in the background.

Quick idea: AI does not mean only robots. AI also includes software systems that can learn from data and make intelligent decisions.
