    Study Notes

    Network Topology

    • Network Topology is the configuration or layout of a network.
    • It defines the paths between any two points in a network.
    • It influences network performance, particularly availability, speed, and traffic congestion.

    Basic Topology

    • Mesh Topology
      • Provides multiple paths between end nodes.
      • Failure of an intermediate node may slow down network traffic but will not stop it as long as alternative paths exist.
      • All nodes are connected to each other.
    • Bus Topology
      • All devices are connected to a single cable called a bus.
      • Data is transmitted in both directions.
      • Relatively inexpensive to implement since fewer cables are required.
    • Star Topology
      • All devices are connected to a central device (e.g. hub or switch).
      • Data is passed through the central device.
      • Easy to add or remove devices.
    • Ring Topology
      • Devices are connected in a closed loop.
      • Data travels in one direction around the ring.
      • Offers high bandwidth and fault tolerance.
