13.  Governments provide various scholarships to students of different classes. Prepare a report on how blockchain technology can be used
              to promote accountability, transparency and efficiency in distribution of scholarships?
         Ans.   We can define blockchain as a system that allows a group of connected computers to maintain a single updated and secure ledger. Each
              computer or node that participates in the blockchain receives a full copy of the database. It maintains an ‘append only’ open ledger
              which is updated only after all the nodes within the network authenticate the transaction. Safety and security of the transactions are
              ensured because all the members in the network keep a copy of the blockchain and so it is not possible for a single member of the
              network to make changes or alter data.
                To facilitate government scholarships for students across various classes, a dedicated ledger is established for each individual. This
              ensures enhanced transparency and efficiency automatically. Students can access and avail their scholarships through their respective
              ledgers, contributing to more authentic and accountable transactions.
          14.  How IoT and WoT are related?
         Ans.   IoT  (Internet  of  Things):  The  Internet  of  Things  refers  to  the  network  of  physical  devices,  vehicles,  appliances,  and  other  objects
              embedded with sensors, software, and connectivity that enables them to connect and exchange data. These devices can range from
              everyday household items like refrigerators and thermostats to industrial machinery and even entire smart cities. The key aspect of IoT
              is the ability of these devices to communicate with each other and with humans, making our lives more convenient and efficient.
                WoT (Web of Things): On the other hand, the Web of Things focuses on the integration of these devices into the World Wide Web. It
              aims to create a semantic web where devices can not only communicate with each other but also with web services and applications.
              This means that WoT enables devices to have their own unique web addresses, making them accessible and controllable through web
              protocols. In simpler terms, WoT allows devices to be part of the internet in a more direct and interactive way.
                In short, IoT primarily focuses on the connectivity and communication between devices, while WoT takes it a step further by integrating
              these devices into the web itself. While IoT is more concerned with the physical layer of devices, WoT is concerned with the application
              layer, enabling devices to interact with web services and applications.
