Some main areas of application of AI are:
                    Natural  Language  processing: It is the study  of methods  by which
                   computers can recognize and understand spoken or written human
                   language. Speech recognition software are an example of NLP where
                   computers translate spoken speech into text.                            Natural Language processing


                                             Pattern  recognition:  This type  of software comprises  of a camera
                                           and  software  which together  identify  repetitive  patterns  and  establish
                                           connections between the patterns stored in the database and the perceived
                                           patterns.  Facial  recognition  software, video  surveillance cameras,
                                           fingerprint identification  and automatic  voice  recognition  software are
                                           some examples of pattern recognition software.

                   Robotics: Shakey  was the  first robot  to  use  AI to  navigate.  It was
                   developed in 1970. There are so many robots that use AI such as Rosie
                   and Roscoe are used in hospital to supply medicines, Robodoc performs
                   hip implant surgeries, Roomba and Scooba can do housework such as
                   cleaning the floor, etc.                                                           Robotics


                                             Intelligent Apps (I-Apps): Intelligent Apps are software written for mobile
                                           devices based  on Artificial Intelligence and machine  learning  technology,
                                           aimed at making everyday tasks easier. This involves tasks like organizing
                                           and prioritizing emails, scheduling meetings, logging interactions, content,
                                           etc. Some familiar examples of I-Apps are Chatbots and virtual assistants.

                        BLOCKCHAIN


                 Blockchain refers to the system of recording information which makes it difficult or impossible to
                 change, hack, or cheat the system. Every business runs on information and blockchain is a shared
                 ledger on which we record the transactions and track assets (tangible or intangible) in a business
                 network. Tangible  assets  include  houses, cars, cash,  lands,  etc.  and non-tangible  assets  include
                 intellectual property, patents, copyrights, branding, etc.
                 It is  a digital  ledger  of transactions  that  is  duplicated  and distributed  across  the  entire  network
                 of computers on the blockchain. Each block in a chain may contain the record of the number of
                 transactions made and the occurrence of new transactions. This record of every transaction is updated
                 and added to the participant’s ledger. Anything that carries value can be recorded and tracked and

                 can be traded on a blockchain network.
