Computer Network Topology

Network topology defines the interconnections between nodes or links etc..for example LAN which consists of two topology's physical and logical. Network topology is determined by the graphical mapping of the configuration of physical and logical connections between nodes or links. As we know that computer system connected with various buses, switches, memory controllers and direct memory access etc..They implements various physical interconnections and transmission rates. So, there are different types of topologies such as Bus topology, Star topology, Ring topology, Tree topology and Hybrid topology etc.. We can also defines the network topologies as follows:

  • Physical topologies: It consists interconnections of various wiring, cables and wiring system which further Classified into different links like Point-to-point, circuit or packet-switching technologies, Bus, Star, Rings and hierarchical networks.

  • Logical topologies: The logical defines the same classifications as in the physical classifications of network topologies.

We provide high quality, professional look of information about computer networking to help you out. Online-widget.blogspot.com specializes in computer Network topology. Hybrid networks defines two or more topologies combination. For example, a tree network connected to various sub tree network. A linear topology link between one computer and the next since each computer required two receivers and two transmitters.
