BLOCKCHAIN

                  Blockchain is a decentralised system of recording information that makes it nearly impossible
                  to alter, hack, or cheat the system. Blockchain can be used in businesses where data integrity,
                  transparency, and traceability are essential. It is a shared ledger that records transactions and
                  tracks assets (tangible or intangible) within a business network. Tangible assets include houses,
                  cars,  cash,  land,  etc.,  and  intangible  assets involve intellectual  property,  patents,  copyrights,

                  branding, etc.
                  The  blockchain duplicates and  distributes a  digital ledger  of transactions  across the  entire
                  network of computers. Each block within a chain stores a cryptographic hash of the previous
                  block, timestamp, and transaction data, ensuring immutability. This record of every transaction is
                  updated and added to the participant’s ledger after consensus is reached. A blockchain network
                  can record, track, and trade anything that carries value.

                         Artificial Intelligence (AI) is a branch of computer science that aims to create computers and
                       machines which are as intelligent as human beings.

                         Robotics is a branch  of engineering  that  deals with  the design, construction,  operation  and
                       application of robots.

                         Robotic Process Automation (RPA) is a software robot running on physical or virtual machine that
                       mimics human actions.

                         Machine Learning (ML) is a technology that allows computer systems to learn patterns based on
                       the data and make predictions or give decisions based on that learned pattern.
                         Data  Science is a field of study that  combines domain expertise,  programming  skills  and

                       knowledge of mathematics and statistics to extract meaningful insights from data.

                         Internet of Things (IoT) describes the network of physical devices that have unique identifiers
                       (UIDs) and can communicate with other devices over the network.

                         Edge computing is a complimentary approach to cloud computing. It keeps computer data close
                       to the user.

                         Augmented Reality is a technology that superimposes sounds, images and text on the real world
                       that we can see.
                         Virtual Reality is a technology that creates a complete virtual world that users can interact with.
                         3D Printing or 3-Dimensional Printing is a process of making a physical object from a digital
                       three-dimensional model.
