Consists of at least 3 computers linked together by means of telecommunication media. Are usually tailored to match the structure of a given establishment, business, or any organization. Each computer in the network is known as a node or a workstation. If the network has a server, all other nodes are considered clients. Star topology: typical client-server network, nodes (clients) are centralized around a server, the topology most frequently used in network technology. Bus topology: consists of a backbone cable (bus) all along the network area, no server, nodes share files and other info, easy to connect and monitor network. Ring topology: several computers connected as a ring, a bus network but with both ends linked together, message flows and priorities go clockwise.
