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
