Communication: Networking allows people to talk to each other through email, messages,
                    and video calls. It helps teams in different places work together easily.

                    Cost-Effective: Buying separate software for each computer can be expensive. Storing it on
                    one server and sharing it with other computers is cheaper.
                    Security: Security tools like firewalls and passwords are needed to protect data and systems
                    from being hacked or misused.
                    DIFFERENT TYPES OF NETWORKS


                 Computer networks come in different sizes, from small home or office networks linking a few devices
                 to the large Internet connecting millions globally. These connections can be 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.




                                                        Campus Area Network  (CAN):  A  CAN  is  a  network  that
                               Hostel                 connects multiple LANs within a university campus, corporate
                                                      campus,  or  industrial  park.  CANs  provide  high-speed
                                           Lab        connectivity  and  centralised  management  of  resources
                  College
                                                      across multiple locations.
                                                                                               Workstation
                               Library
                    Local  Area Network (LAN):  A Local  Area  Network  (LAN)
                    connects computers within a small area, like a room, floor,
                    school, or office building. It can be wired with Ethernet or
                    optical fibre cables, or wireless using Bluetooth or Wi-Fi.

                    Metropolitan  Area Network  (MAN):  A Metropolitan  Area  Network  (MAN)  connects
                    computers within a city, such as branches of the same organisation. It is typically owned by
                    one entity, like a government body or large company. It spans a physical area larger than a
                    LAN but smaller than a WAN.
