                                          Local Area Network (LAN)

                                          A LAN connects devices within a small area, such as a home, office, or
                                          school. It allows devices to share files and resources like printers. LANs
                                          typically use wired connections, though wireless LANs (Wi-Fi) are also
                                 Server   common.


                 Wide Area Network (WAN)


                 A WAN connects multiple LANs over a large geographical area, such as a city, country, or even
                 across continents. The Internet is the most well-known example of a WAN.

                 Metropolitan Area Network (MAN)


                 A MAN covers a larger area than a LAN but is smaller than a WAN. It typically connects networks
                 within a city or a large campus.

                 Personal Area Network (PAN)

                 A PAN is a small network used for personal devices like smartphones,
                 laptops, and tablets. It usually covers a very small area, such as the
                 range of a Bluetooth connection or Wi-Fi network.
                 Virtual Private Network (VPN)

                 A VPN creates a secure connection over a less secure network, like the Internet. It is often used
                 to allow remote workers to access a company’s internal network securely.
