Need for Networking

                  Networking the computers is becoming a basic need of today’s world. Some of the main reasons
                  to connect the devices into networking are:
                      Sharing of Resources: The primary goal of computer networking is to share resources, such
                     as printers, scanners, modems, etc. This enables efficient use of resources and reduces the
                     need for duplicate equipment or software. For example, several PCs can be connected to a
                     single printer.
                      Communication:  Networking  facilitates  communication  between  individuals  and  groups
                     through email, instant messaging, video conferencing, and other communication tools. This
                     promotes  real-time  interaction,  and  enables  remote  collaboration  among  geographically
                     dispersed teams.

                      Cost Effective: Individually licenced copies of many popular software programs can be costly.
                     Storing the software on a file server and then making it available to the other computers
                     connected to it will be cost-effective.
                      Security: Implementing security measures such as firewalls, encryption, and access controls is
                     essential for protecting data, systems, and networks from unauthorised access, attacks, and
                     breaches. Centralised security management and monitoring can effectively shield the data
                     away from online threats.

                     DIFFERENT TYPES OF NETWORKS

                  There are different kinds of computer networks that work in different ways. Networks can be
                  as small as a home or office network, connecting a few devices, or as large as the Internet,
                  which connects millions of devices all across the globe. Connections between computers on the
                  network can be either wired or wireless.
                  Some of the common types of networks are:

                      Personal Area Network (PAN): A PAN is a network that connects devices within the personal
                     range of an individual, such as smartphones, tablets, laptops, and wearable devices. Bluetooth
                     and infrared are common technologies used for PANs.
