12/3/2023 0 Comments Network topology diagram examples![]() This is different from physical topology as it does not explain the physical wiring of a network, but instead, it describes the flow of data, information, and back, from one system to another and the routes it takes. ![]() It tells about a network that should be configured for the transfer of information. The network equipment and cabling layout floorplan template for the ConceptDraw PRO diagramming and vector drawing software is included in the Network Layout Floor Plans solution from the Computer and Networks area of ConceptDraw Solution Park.The network topology is a structure or the physical arrangement of the network devices, how the components of the network are interconnected with each other. Power line communication uses a building's power cabling to transmit data.Īpart from the physical communications media described above, networks comprise additional basic system building blocks, such as network interface controller (NICs), repeaters, hubs, bridges, switches, routers, modems, and firewalls." those defined by IEEE 802.11) use radio waves, or others use infrared signals as a transmission medium. Ethernet transmit data over both copper and fiber cables. The media and protocol standards that enable communication between networked devices over Ethernet are defined by IEEE 802.3. In the OSI model, these are defined at layers 1 and 2 - the physical layer and the data link layer.Ī widely adopted family of communication media used in local area network (LAN) technology is collectively known as Ethernet. The communication media used to link devices to form a computer network include electrical cable (HomePNA, power line communication, G.hn), optical fiber (fiber-optic communication), and radio waves (wireless networking). Nodes can include hosts such as personal computers, phones, servers as well as networking hardware. Network computer devices that originate, route and terminate the data are called network nodes. The connections (network links) between nodes are established using either cable media or wireless media. "In computer networks, networked computing devices pass data to each other along data connections. The network layout floorplan template for the ConceptDraw PRO diagramming and vector drawing software is included in the Network Layout Floor Plans solution from the Computer and Networks area of ConceptDraw Solution Park. For example, a common practice in a campus of buildings is to make a set of LAN cables in each building appear to be a common subnet, using virtual LAN (VLAN) technology." ![]() Logical networks, called, in the TCP/ IP architecture, subnets, map onto one or more physical media. The physical perspective involves geographic locations, physical cabling, and the network elements (e.g., routers, bridges and application layer gateways) that interconnect the physical media. Network administrators can see networks from both physical and logical perspectives. A community of interest has less of a connection of being in a local area, and should be thought of as a set of arbitrarily located users who share a set of servers, and possibly also communicate via peer-to-peer technologies. Users can share printers and some servers from a workgroup, which usually means they are in the same geographic location and are on the same LAN, whereas a Network Administrator is responsible to keep that network up and running. Users and network administrators typically have different views of their networks. Two such devices are said to be networked together when one device is able to exchange information with the other device, whether or not they have a direct connection to each other. In computer networks, networked computing devices pass data to each other along data connections. "A computer network or data network is a telecommunications network that allows computers to exchange data.
