  • It is the arrangement with which computer network devices or systems are connected to each other.
  • The topologies divided into two types they are physical and logical topology.
  • It can be also simply defined as a schematic description of a network’s elements’ arrangement.
  • Physical network topology illustrates the physical connections within your network while logical network topology illustrates how data flows between your network’s devices, such as its computers and cables.
  • Visual diagrams can be used to represent physical and logical topologies, depending on your needs—either can be useful for understanding your network and its layout.
  • There are several types of network topology, they are
      1. Bus topology
      2. Ring topology
      3. Tree topology
      4. Star topology
      5. Mesh topology
      6. Hybrid topology

    Bus topology

    • In network it consists of one continuous length of cable that is shared by all the nodes.
    • At each end it has a terminating resistor that absorbs the signal when it reaches the end of line.

    Ring topology

    • In this topology each node has two neighboring nodes.
    • From one neighboring data packet is received and transmitted to the next.
    • The data travels like ring structure in one direction so that it is called as ring topology.

    Star topology

    • Directly each node connected to a central network hub or concentrator.
    • Before continuing data passes through hub or concentrator.
    • All functions of network control and managed by hub or concentrator.

        

    Tree topology

    • This type topology combines the characteristics of linear Star and Bus topology. It inverted like tree structure.
    • It consists of groups of star-configured workstations connected to a linear bus backbone cable.

    Mesh topology

    • In mesh topology each computer is connected to another computer through network.
    • This topology has hosts which are in point-to-point connection to few hosts only or hosts in point-to-point connection with every other host.

         

    Hybrid topology

    • It is an integration of two or more different topologies to form a resultant topology.
    • Hybrid topology inherits demerits and merits of all incorporating topologies.
    • The combining topologies may contain attributes of Ring, Star, Daisy-chain and Bus topologies.
