Describe the different types of network topologies.

  1. Bus Topology:
    • Description: In a bus topology, all devices are connected to a central communication channel called the bus. The devices share this single communication line.
    • Technical Details:
      • Advantages:
        • Simple and easy to implement.
        • Cost-effective for small networks.
        • Suitable for linear and small-sized networks.
      • Disadvantages:
        • Limited scalability as adding more devices can lead to performance degradation.
        • Single point of failure (if the central bus fails, the entire network goes down).
  2. Star Topology:
    • Description: In a star topology, all devices are connected to a central hub or switch. The hub or switch acts as a repeater for data flow.
    • Technical Details:
      • Advantages:
        • Easy to install and manage.
        • Centralized control and easy to identify and isolate problems.
        • No disruption to other devices if one device fails.
      • Disadvantages:
        • Dependency on the central hub; failure of the hub disrupts the entire network.
        • Costlier due to the need for a central device.
  3. Ring Topology:
    • Description: In a ring topology, each device is connected to exactly two other devices, forming a closed loop.
    • Technical Details:
      • Advantages:
        • Data travels in one direction, reducing collisions.
        • Simple and easy to install.
      • Disadvantages:
        • Failure of one device can disrupt the entire network.
        • Difficult to troubleshoot and reconfigure.
  4. Mesh Topology:
    • Description: In a mesh topology, every device is connected to every other device in the network, creating multiple paths for data transmission.
    • Technical Details:
      • Advantages:
        • Robust and fault-tolerant; multiple paths ensure network stability.
        • High scalability and reliability.
      • Disadvantages:
        • High implementation cost due to numerous connections.
        • Complex to install and manage.
  5. Hybrid Topology:
    • Description: Hybrid topology is a combination of two or more different types of topologies.
    • Technical Details:
      • Advantages:
        • Offers flexibility and scalability.
        • Allows for optimizing the network based on specific requirements.
      • Disadvantages:
        • Complex to design and manage.
        • Costlier due to the combination of different topologies.
  6. Tree Topology:
    • Description: Tree topology combines characteristics of star and bus topologies, forming a hierarchy.
    • Technical Details:
      • Advantages:
        • Scalable and can cover larger areas.
        • Allows for easy management and troubleshooting in smaller segments.
      • Disadvantages:
        • Dependency on the root node; failure can affect the entire branch.
        • Complex to design and install.
