Artificial Intelligence is the concept of making machines behave like humans. It aims to provide
capabilities to machines that allows them to mimic human intelligence and display behaviour that is
similar to humans. But the definition of Artificial Intelligence, or AI as it is commonly called, changes
with context and has indeed done so since its inception.

DEFINING ARTIFICIAL INTELLIGENCE
Let us look at some definitions of Artificial Intelligence as proposed by different scientists and computer
developers.
1. AI can be defined as a branch of computer science dealing with the simulation of intelligent
behaviour in computers.

2. It can also be defined as the capability of a machine to imitate intelligent human behaviour.
3. Artificial Intelligence is the science and engineering of making computers behave in ways that
require human intelligence.
4. Artificial Intelligence is the ability of certain machines to do things that people are inclined to call
intelligent.

All the above definitions have one point in common – machines doing something that is in the domain
of human intelligence. But what are the actions or tasks a machine should perform that will qualify it to
be called ‘Intelligent’? The answer to these changes with the discipline of study to which AI is applied.
