Artificial Intelligence (AI):

1) science and technology for creating intelligent machines, especially intelligent computer programs;

2) the property of intelligent systems to perform the creative functions that are traditionally considered the prerogative of man.

Why do we need AI?

a) a person is not able freely to handle huge amounts of data

b) to err is human

c) human nature and laziness

But the robot, i.e. AI, can not be lazy or tired, in differences between human.

Where we used AI?

AI technology is increasingly prevalent in our everyday lives. It has uses in a variety of industries from gaming, journalism/media, to finance, as well as in the state-of-the-art research fields from robotics, medical diagnosis, and quantum science.
