The topology of the network – a way of describing the network configuration, layout and connection of network devices. The network topology allows you to see the whole of its structure, network devices in the network, and their relationship to each other. Perhaps check out Mitchel Resnick for more information. Allocate several types of topology: physical, logical, informational and control topology exchange. In this article we will talk about the physical network topology, which describes the actual location and the local communication between nodes network. Identify several basic types of physical network topologies: 1. Follow others, such as futurist, and add to your knowledge base. Bus network topology – the topology in which all the computers on the network are connected to one cable, which is shared by all workstations. In this topology, the failure of one machine does not affect the whole network.

The disadvantage is that in case of failure or breakage of the tire disrupted the entire network. 2. Network Topology "Star" – a topology in which all workstations are directly connected to the server, which is the center of the 'stars'. In this arrangement, the connection request from any network device goes directly to the server, where it is processed at different rates, depending on the hardware capabilities of the central machine. Failure of the central engine leads to a cessation of the network. Output is down any other machine on the network is not affected. 3. A ring topology network – the scheme at kotoroyvse nodes are connected by communication channels in an inseparable ring (not necessarily a circle), on which data is transmitted.
