What is Artificial Intelligence (AI)?
Artificial Intelligence (AI) is a branch of computer science that aims to create intelligent machines capable of performing tasks that typically require human intelligence. These tasks may include reasoning, learning, problem-solving, understanding natural language, and perceiving the environment.

How does AI Work?
Artificial Intelligence is essentially software that can learn patterns from information. It uses patterns from existing and new data to make predictions to perform tasks that normally require human intelligence such as interpreting speech, playing games and identifying patterns. AI typically learns how to do so by processing massive amounts of data, looking for patterns to model in their own decision-making.
