The banking system is a very good example of a WAN network. These computers save data at real time, send queries to server and fetch reports at the same time. All the computers on the network are connected to central database on the server.
The name of this computer is server because it is there to serve all the computers on the network. On WAN, the users at different locations are connected to a central server. To secure this network, the Network Administrator uses routers and firewalls to secure the network. A VAN can be established by buying Live IPs from the service provider, at two or more different locations. Today, many companies are establishing Virtual Private Network (VAN) by using leased lines. The businesses and institutions get leased lines from different service providers and pay them on monthly basis. Most companies use leased lines as very limited companies can bear the cost of thousands pounds for it. You can either lay down your own cables between two or more locations or you can use leased lines. There are many ways to build a Wide area network. WAN connects two or more LANs, and this is possible with the use of devices like routers. On domain, you have the privilege to grant permissions to users to share resources or limit them to use certain services.Īs LAN can only work within a certain distance, we need WAN to connect institutions and offices at different locations. You can either make this network a workgroup (share limited resources) or domain (share all kind of resources and services). The computers on a Local Area Network are connected to a network switch. One example is a network of a university or a business office at one location.
Local Area Network, as the name suggests, is a network built in a limited area by using LAN cables, switches and LAN cards. Before we look into Wide Area Network (WAN), we must have an understanding of what is Local Area Network (LAN). Those who find it difficult to get idea of wide area network, internet is one live example of it. Internet was never possible without the invention of intelligent switches, satellites, fibre optic cables and LAN cards. Local Area Network (LAN) Pros Wiring does not need to be replaced but switches and routers may need to.

Description: This is a PDF file of a presentation about the limitations, advantages and disadvantages of different types of networks. A computer network is defined as the interconnection of two or more. The biggest advantage of MANs is the bandwidth (potential speed).
