First of all, WAN is an acronym for Wider Area Network. A good example of a WAN is the Internet. The basic components of a WAN would be routers, satellites, ISP mainframes, transmission media (Fiber Optics backbones, Power lines, network cables etc....i suppose satellites would also be classed as a transmission media). The most essential of an WAN Component can be Modems / Routers / Router abd Firewalls.
Are they located in the same building? If the geographical difference between locations are vast, then a WAN setup is in order. The basic components of a WAN would be routers, satellites, ISP mainframes, transmission media (Fiber Optics backbones, Power lines, network cables etc). The main component of a WAN is definitley a router though.
there are a few different topologies when you are talking about WAN's but remember WAN's topologies are different than LAN's because of the area they cover. But there are bus wan, ring wan, star wan, full mesh wan, partial mesh wan, and tiered wan. as far as a drawback to bus topology is that each site in the wan bus topolgy depends on every other site in the network to transmit and receive its traffic.
