Personal Area Network (PAN)

              A  PAN  is  the  simplest  and  most  basic  sort  of  network,  consisting  of                        a
              wireless modem, one or more computers, phones, printers, tablets, and
              other devices that revolve around one person in one building. These
              networks are commonly found in small offices or homes, and they are
              controlled by a single person or organisation using a single device. The
              range of PAN is 10 meters.




                                                  Local Area Network (LAN)

                                                  LANs are one of the most commonly used networks, as well as one of the
                                                  most prevalent, unique, and basic forms of networks. These networks allow
                                                  groups  of  computers  and  low-voltage  devices  to  share  information  and
                                                  resources over a radius of up to 1 KM (inside a building or between two or
                                                  three buildings near each other). This type of network is generally maintained
                                                  by an organisation. Its speed ranges from 10 Mbps to 1 Gbps.


              Metropolitan Area Network (MAN)

              A MAN is larger than a LAN or we can say that it is a combination of multiple LANs. A single entity or a group of persons
              or organisations may own a MAN. It is used to create connections within a city and can cover a radius of up to 50 KM.
              By connecting several local area networks, a MAN makes resource sharing easier. One of the best examples of MAN is
              a cable television network within a city.

                                                                LAN





              Wide Area Network (WAN)

              A WAN, which is slightly more complicated than a LAN, connects computers over longer physical distances. It enables
              computers and low-voltage devices to communicate over a single huge network even when they are thousands of
              kilometres distant. It establishes links within a country or continent by connecting several local and metropolitan area
              networks. The Internet is the most fundamental type of WAN, as it connects millions of computers worldwide. A WAN
              is often owned and maintained by many administrators or the general public because of its extensive reach.
