    A  network is a system of interconnected  nodes  that  exchange information,  resources  or
                      services.  These nodes  can be  computers,  people,  organisations  or places  linked  to  enable
                      communication and interaction.

                      Networks can be classified into various types:

                         Computer networks connect devices to share data and Internet access.

                         Social networks link people for sharing information and staying connected.

                         Transportation networks connect locations through roads, railways and air routes to move
                         people and goods.

                      Overall, networks the backbone of connectivity. They improve  efficiency, support collaboration
                      and enhance interaction across technology, society, transport and ecosystems.

                                COMPUTER NETWORKS

                      A  computer network is  a  group  of computers
                      and other devices  (such as printers, smartphones

                      and tablets) connected to  share resources  and
                      information. Networks allow devices to communicate
                      with each other, share files and access the internet.
                      Computer networks make everyday tasks easier and
                      improve the speed and efficiency of communication.

                                                                  PURE
                        The first  computer  network was
                        developed in the 1960s.                   FACT

                      ADVANTAGES OF COMPUTER NETWORKS

                      Some advantages of computer networks are as follows:
                         They allow users to share data, software and hardware devices.
                         They help reduce costs as the same devices can be used by many users.

                         Communication becomes faster and easier through emails, chats and online tools.
                         If some computers fail, data can still be accessed from other devices on the network.

                      NETWORKING TERMINOLOGIES
                      Some commonly used networking terms include:

                         Client: This is a system  or device  that  uses services  and resources  provided  by  a server
                         in a network.
