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.



                      ARTIFICIAL INTELLIGENCE


            You have already read about Artificial Intelligence in earlier classes. AI is the branch of computer
            science that aims at creating expert and intelligent computer systems which simulate certain
            human qualities such as, learning, reasoning, communicating, seeing, hearing, and sensation.
            So, AI is used to create intelligent machines that help us. AI is a part of almost everything we use
            today such as smartphones, cars and banks. Some main areas of application of AI are:

                Expert System: It can be defined as a communicating
                                                                                                User
              computer  program  that  can solve problems  which                               Interface
              would otherwise require human assistance.  These                                           User (not
              programs replicate the reasoning process of experts                              Inference   an expert)
                                                                                               engine
              in certain areas. For example, PROSPECTOR was the
              first expert system that analysed geological data to                            Knowledge
                                                                                                base
              identify and locate mineral deposits.                       Human    Knowledge
                                                                           expert   engineer
                                                                                           Expert system

                                             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

             Natural language processing  where computers translate spoken speech into text.
               Intelligent Agents: It is a type of computer program that has built-
              in intelligence which keeps  a check  on the work  patterns,  asks
              questions and performs tasks on the behalf of the user. The simplest

              example of intelligent agents is surfing the Internet. What happens
              when we search for something on the Internet?
                                                                                             Intelligent agents
