![]() Typically, networking hardware includes gateways, routers, network bridges, switches, hubs, and repeaters. Specifically, they mediate data in a computer network. Units which are the last receiver or generate data are called hosts or data terminal equipment.Īll these terms refer to devices facilitating the use of a computer network. "Networking hardware may also be known as network equipment or computer networking devices. The vector stencils library "Network hardware" contains 27 clipart images and symbols of network equipment for drawing computer network diagrams. This hybrid satellite and common carrier network diagram example was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Telecommunication Network Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park. They are also used for mobile applications such as communications to ships, vehicles, planes and hand-held terminals, and for TV and radio broadcasting." Modern communications satellites use a variety of orbits including geostationary orbits, Molniya orbits, elliptical orbits and low (polar and non-polar) Earth orbits.įor fixed (point-to-point) services, communications satellites provide a microwave radio relay technology complementary to that of communication cables. "A communications satellite or comsat is an artificial satellite sent to space for the purpose of telecommunications. The computer network topologies diagram example was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park. The study of network topology recognizes eight basic topologies: Point-to-point, Bus, Star, Ring or circular, Mesh, Tree, Hybrid, Daisy chain." ![]() Distances between nodes, physical interconnections, transmission rates, and/ or signal types may differ between two networks, yet their topologies may be identical. Physical topology refers to the placement of the network's various components, including device location and cable installation, while logical topology shows how data flows within a network, regardless of its physical design. Essentially, it is the topological structure of a network, and may be depicted physically or logically. "Network topology is the arrangement of the various elements (links, nodes, etc.) of a computer network.
