Metropolitan Area Network (MAN)

            A MAN is a network which covers more area than a
            LAN. It is spread across a city. As it covers a city, it is
            known  as  metropolitan  area  network.  Cable
            television, branches of local banks within a city, etc.
            are some common examples of MAN type network.




                                             Wide Area Network (WAN)
                                             A WAN is a global computer network that is spread across cities,

                                             countries, or continents. It is formed by connecting various LANs
                                             and MANs.






            Personal Area Network (PAN)

            A PAN is a computer network which is organised around a
            person. It is used for communication between devices such as
            printers,  phones,  PDAs,  and  laptops  that  are  in  close
            proximity.

                The Internet is considered to be the largest Wide Area Network (WAN).



            NETWORK ARCHITECTURE

            Network architecture is an overall design of a computer network. The architecture of a network
            can be defined as the structure and organisation of the computer's hardware and software.
            On the basis of architecture, network can be classified into two types:

                 1. Client-Server Network           2. Peer-to-Peer Network (P2P)


                                                     Client-Server Network

                                                     It is a network where several computers called clients or
                                                     workstations are connected to the main computer called the
                                                     server.

                                                     A  computer  which  provides  services  to  the  clients  and
                                                     controls  the  access  to  hardware,  software  resources  and
                                                     other resources, is called the Server  .

            The computers which request services like data retrieval, storage, etc. from the server is called the
            Client.

                                                                 8
