               As more and more new technologies get into play, risks  will get more concentrated into a common network.
              Cybersecurity becomes extremely complicated in such scenarios and goes beyond the control of firewalls. It will not be
              able to detect unusual activity and patterns including the movement of data.
               Think how AI algorithms can scrape through vast amounts of logs to identify susceptible user behaviour. Use an AI
              project cycle to clearly identify the scope, how you will collect data, model and evaluation parameters.
           20.  Scenario: The world of Artificial Intelligence revolves around Data. Every company, whether small or big, is mining data
              from as many sources as possible. More than 70% of the data collected till now has been collected in the last 3 years
              which shows how important data has become in recent times. It is not wrongly said that Data is the new gold. This
              makes us think. Answer the following questions:
               a)  Define data.
               b) Under which step of the AI Project Cycle does data collection come?
               c) Where are the various ways of collecting data?
               d) Name the reliable websites to collect data.
               e) “It is not wrongly said that Data is the new gold.” Justify.                                  4
           21.  Explain the working of Neural Networks and also write down it's applications.                   4
