Access to remote databases
                 Today, every person can easily access databases from remote locations, such as when booking tickets, paying bills,
                 checking results, etc., because of networking. When we book a train ticket, we indirectly interact with the database of
                 the railways. Networking plays a vital role in accessing remote databases. The computer on which the databases stored
                 is known as database server.

                 Requirements of a Network
                 Let us now look at what are the requirements of a network. Any network includes:

                 Ð ÐComputer: Minimum two computers, one for server and other for client workstation, are required to form a network.
                 Ð ÐConnection Medium: A connection medium, often a wire or cable, although wireless communication between
                   networked computers and peripherals is also feasible. Connection medium can be wired (cable) or wireless (wi-fi).

                 Ð ÐNetworking Device: A networking device through which all the computers are connected with the network is
                   required.
                  ÐOperating System: Software like Windows Server, Novell NetWare, Unix, and Linux are some of the examples of the
                 Ð
                   operating systems for networking.

                 Advantages of a Network

                 A network offers several advantages. Some of them are as follows:
                 Ð ÐResource sharing: Networks enable users to share devices like printers and scanners, allowing multiple users to
                   access these resources without the need for each individual to own them. For example, a single printer can serve
                   an entire office, significantly reducing costs.

                  ÐData sharing: Users can easily share files and information across the network, which enhances collaboration and
                 Ð
                   productivity. For instance, team members can work together on shared folders stored on a central server, ensuring
                   everyone has access to the latest documents.

                 Ð ÐCommunication: Networks facilitate various forms of communication, including emails, instant messaging, and
                   video conferencing. This allows teams to connect in real-time, as seen with applications like Zoom or Microsoft
                   Teams, which support remote collaboration.

                 Ð ÐCentralised data management: Storing data in a central location makes it easier to manage, back up, and secure
                   information. Organsations often utilise centralised databases that allow all employees to access and update data
                   efficiently.

                 Ð ÐIncreased storage: Networks provide access to centralised or cloud storage, allowing users to store large amounts
                   of data without depending solely on local devices. Services like Google Drive or Dropbox enable users to save and
                   share files conveniently.
