    The  Network topology is defined by two types — physical topology and the logical topology. While physical topology talks more about the geometry and physical placement of the tools on the same hand, logical topology is more about the way data communication or signaling happens among the devices.

    Network Topology

    The Network topology is the arrangement of the various networking elements like network links, computers, switches, nodes, Wi-Fi access points, laptops and other network devices in a computer network.

    What is Physical topology?

    Physical topology defines how all the network devices are connected physically in a computer network. It mostly defines the physical connections among the devices.

    Types of Physical Topology

    Topology Description
    Bus topology In the bus network topology, every node is connected in series along a linear path.

    Star topology In the star network topology, a central node has a direct connection to all other nodes.

    Ring topology In the ring network topology, the nodes are connected in a closed loop configuration.

    Tree topology It has a root node and all other nodes are connected to it forming a hierarchy. The tree network topology is a network where star topologies are themselves connected in a star configuration.

    Mesh topology This topology is a point-to-point connection to all other nodes or devices.

    Hybrid topology It is a combination of two or more different types of topology.

    What is a Logical topology?

    A logical topology defines the logical connectivity of network devices on an Abacus network. So, it could happen that the devices connected in one type of physical topology might have different hidden logical topology.

    If we busy more on the physical topology, it is actually the placement of the various network components in a computer like the employment of the devices, the relation among the devices, installation of the cables, etc. On the other hand, the logical connection defines how data flows among the devices.

    For example, let say there are five devices (A, B, C, D and E) that are connected in a row. This configuration of network devices might look more like a Bus topology. But let’s say device A can directly transmit the data to the device E. That means it looks more like a Circle which a Ring topology logically but a bus topology physically.

    Different network topologies have different advantages and disadvantages. A bus network topology is nice because it is simple and cheap, however, it has its limitations.
