Network topologies

Network topology refers to the arrangement of various elements (like nodes and links) in a communication network. Here are some common types of network topologies:

  1. Bus Topology: All devices are connected to a single central cable, called the bus. Data sent from a device travels along the bus until it reaches its destination. It’s simple and cost-effective but can be slow and prone to collisions.

  2. Star Topology: All devices are connected to a central hub. The hub acts as a repeater for data flow. It’s easy to manage and expand, but if the hub fails, the entire network goes down.

  3. Ring Topology: Each device is connected to two other devices, forming a circular data path. Data travels in one direction, reducing the chance of packet collisions. However, if one device fails, it can affect the entire network.

  4. Mesh Topology: Every device is connected to every other device. This provides high redundancy and reliability, as data can be rerouted if one path fails. However, it’s expensive and complex to set up.

  5. Tree Topology: A combination of star and bus topologies. Groups of star-configured networks are connected to a linear bus backbone. It’s scalable and easy to manage, but if the backbone fails, it can segment the network.

  6. Hybrid Topology: A mix of two or more different topologies. It leverages the strengths and mitigates the weaknesses of the combined topologies, making it flexible and scalable
