TYPES OF NETWORKS IN INTERNET COMMUNICATION peer to peer networks support basic communications between people and sharing of peripheral devices, where as client/server networks support basic communications between people and the sharing of the peripheral devices,softwares,information and processing power. Now lets see most of the two prevalent networks in the modern era, viz, NETWORKS BY GEOGRAPHIC DISTANCE ,in this there are two types local area networks (LANs) covering a limited geographic distance,such as office, building etc. widearea networks (WANs)cover a large geographic distances ,a state ,a country or even the entire world.Regardless of your choice of a LAN OR WAN ,YOU MUST ALSO DECIDE HOW TO PHYSICALLYSTRUCTURE OR arrange the computers in a network .There are three types of TOPOLOGY in computer network. BUS TOPOLOGY- all computers are connected to a single communications mediumover which all communications travel.IF you send a message to another person in a bus topology, that message travels the entire bus. RING TOPOLOGY- all computers are connected to a single communications medium (similar to a bus) and that communications medium is connected at both ends to form a closed loop. STAR TOPOLOGY- this arrangement has a central computer from which all other computers radiate .In this instance, if you send a communication to another person, that communication must pass through the central computer, which in turn , interprets the address and sends the communication appropriately.
