                 Today, Artificial Intelligence (AI) is extensively used by us, however we just unaware about it. Nowadays, we are surrounded
                 by a variety of AI applications that facilitate many aspects of our lives. Have you ever thought that the music we listen to
                 on Spotify, the products we purchase from e-commerce websites, or news and information that we get all are possible
                 with the help of AI? AI helps in poem writing, story writing, helps doctors perform complex surgeries and also prescribes
                 medications.
                 In this unit, we will learn how AI applications helping us. We will learn about the applications of AI in the different fields
                 like science, automobiles, healthcare, trading and business, weather, etc. We will also learn about cognitive computing
                 aspect of AI by introducing the terms like Computer Vision, speech, reasoning, etc.


                        Key Fields of Application in AI

                 According to the father of Artificial Intelligence, John McCarthy, “Artificial Intelligence is the science and engineering
                 of making intelligent machines, especially intelligent computer programs”. These intelligent machines can learn,
                 function and react like humans. Today, AI has become an important part of our lives and used in several fields like
                 science, engineering, business, medicine, video games, etc. Let us discuss some of the applications of AI in detail.

                 Chatbots
                 A chatbot is an AI application that can mimic a real conversation with a user
                 in their natural language. Chatbots allow communication through the text
                 interface  or  audio  on  websites,  messaging  applications,  or  smartphones.
                 The applications of chatbots are immense:
                 •  Retail and E-commerce
                 •  Travel and hospitality
