Network topology is the arrangement of the various elements (links, nodes, etc.) of a computer network. Essentially, it is the topological structure of a network and may be depicted physically or logically. Physical topology is the placement of the various components of a network, including device location and cable installation, while logical topology illustrates how data flows within a network, regardless of its physical design. Distances between nodes, physical interconnections, transmission rates, or signal types may differ between two networks, yet their topologies may be identical.
An example is a local area network
(LAN): Any given node in the LAN has one or more physical links to
other devices in the network; graphically mapping these links results in
a geometric shape that can be used to describe the physical topology of
the network. Conversely, mapping the data flow between the components
determines the logical topology of the network. Continue Reading....
