Understanding Network Topologies

In the realm of computer networks, a network topology refers to the arrangement or layout of the various interconnected devices, nodes, and communication channels that constitute a network. Different topologies offer unique advantages and disadvantages, making them suitable for specific use cases. Understanding the characteristics and distinctions of these topologies is crucial for comprehending the significance of hybrid topology.

Common Network Topologies

Bus Topology: Bus topology is a linear arrangement where all devices are connected to a central cable, known as the “bus.” This topology is simple to set up and cost-effective, making it suitable for small networks. However, a single point of failure can disrupt the entire network, and as more devices are added, performance may degrade.
Star Topology: In star topology, all devices are connected to a central hub or switch. This setup enhances reliability, as a failure in one device doesn’t affect others. It also simplifies troubleshooting and maintenance. However, the central hub becomes a single point of failure, and the cost of installation can be higher due to the requirement for multiple cables.
Ring Topology: Ring topology connects devices in a closed loop, where each device is connected to exactly two other devices. This approach provides balanced communication and prevents collisions. However, a failure in one device or connection can disrupt the entire network, and scalability can be challenging.
Mesh Topology: Mesh topology involves a direct connection between each device in the network. This results in high redundancy and fault tolerance since multiple paths exist for data transmission. However, the complexity of installation and maintenance increases significantly with the number of devices, making it more suitable for critical applications.

Limitations and Advantages of Each Topology

Bus Topology:
