2 Lan Is local area network. is certainly not over a large geographical area. There are four common types of lan network topologies : 1. Ring network: every computer in the network is connected in a ring. 2.Bus network: every computer is connected to a common central line. 3.Star network: every computer is connected via a central hub or switch. 4.tree network: has a central line connecting together a series of star networks. Ring networkbus network star networktree network

3 wan Is wide area network. Is basically formed by a number of lans being connected together through either a router or a modem. Its expensive but comes with the advantage of much enhanced security. The following additional hardware is needed for a wan: routers, modems and proxy servers.
