network Bus network Ring network 14 Network Topology
Network topology is the layout pattern of interconnections of the various elements (links, nodes, etc.) of a computer. Types of network topology Star Bus Ring Hierarchical Networks are connections of two or more computers that work together to exchange information and share resources The network architecture describes how the network is arranged and how the resources are coordinated
and shared Network architecture also describes how a computer network is configured and what strategies are used Topology – network arrangement or configuration 15 Star Network Smaller computers linked to a central
