Artificial intelligence MCQs with Answers : Model Test Paper – I
Artificial intelligence means that we put human thinking power, emotions or say human conscience in the machine. Simply put, Artificial Intelligence is a technique under which robots can think like humans in any situation and make decisions accordingly.
It is worth noting that artificial intelligence no longer includes machines that can analyze situations by looking at the camera, but also includes advanced technology in artificial intelligence, which can understand one’s language, decisions. So that you can share your emotions.
