Which Of The Following Is Not A Common Network Topology

In the ever-evolving world of networking, staying updated with various network topologies is paramount. While some topologies have stood the test of time, others have fallen out of favor due to their limitations or inefficiency. Understanding which network topologies are not commonly used can equip you with valuable insights for making informed decisions about your network’s architecture.

When it comes to network topologies, there are a few that often raise eyebrows due to their uncommon nature. These topologies may have certain drawbacks or complexities that make them less suitable for practical applications. Identifying these uncommon topologies can help you avoid potential pitfalls and select the most appropriate topology for your specific networking needs.

One such uncommon network topology is the hierarchical star topology. This topology involves multiple star networks interconnected to form a larger network. While it offers some advantages like scalability and fault isolation, its complex structure and increased management overhead make it less commonly adopted.

To summarize, the hierarchical star topology stands out as an uncommon network topology due to its intricate structure and management challenges. When selecting a network topology, it’s crucial to consider factors such as scalability, fault tolerance, and ease of management to ensure the best fit for your networking requirements.

Which of the Following Is Not a Common Network Topology?

Network Topology

The interconnectedness of nodes in a network is referred to as network topology. It is a logical arrangement of nodes, links, and paths that define how data flows within a network. There are several common network topologies, each with unique characteristics, advantages, and disadvantages. In this article, we will discuss various network topologies and identify the one that is not commonly used.

Common Network Topologies

  1. Bus Topology

Bus Topology

A bus topology is a simple network layout where all nodes are connected to a single central cable or backbone. Data is transmitted in both directions along the cable, and each node receives and forwards data packets to their intended destinations.

  1. Star Topology

Star Topology

In a star topology, all nodes are connected to a central hub or switch. Data is transmitted from the hub or switch to the nodes, and vice versa. The hub or switch acts as a central point of communication and controls the flow of data within the network.

  1. Ring Topology

Ring Topology

A ring topology connects nodes in a closed loop or ring. Data flows in one direction around the ring, passing through each node. Each node receives and forwards data packets to the next node in the ring until it reaches its intended destination.

  1. Mesh Topology

Mesh Topology

A mesh topology provides multiple paths between nodes, creating a fully connected network. Each node is connected to multiple other nodes, providing redundant paths for data transmission. This type of topology offers high reliability and fault tolerance.

Uncommon Network Topology

  1. Tree Topology

Tree Topology

A tree topology is a hierarchical network layout where nodes are arranged in a parent-child relationship. The topmost node is the root, and the lower nodes are connected to the root or to other nodes in a branching structure. Data flows from the root node to the child nodes and vice versa.

While the tree topology is not as common as the previously discussed topologies, it is occasionally used in certain network scenarios, such as hierarchical networks or wide area networks (WANs).

Conclusion

In conclusion, the most common network topologies include bus, star, ring, and mesh topologies. These topologies are widely used in various network environments due to their simplicity, reliability, and scalability. Tree topology, on the other hand, is not as commonly encountered as the other topologies, although it can be employed in specific network scenarios. The choice of network topology depends on factors such as the size of the network, the required performance, and the cost considerations.

Frequently Asked Questions (FAQs)

  1. Which topology offers the highest level of fault tolerance?

    Mesh topology provides the highest level of fault tolerance due to its multiple paths between nodes. If one path fails, data can be rerouted through alternative paths, ensuring uninterrupted communication.

  2. What is the primary advantage of a star topology?

    The primary advantage of a star topology is its simplicity and ease of management. It is easy to add or remove nodes without disrupting the entire network, making it a popular choice for small to medium-sized networks.

  3. What is the main disadvantage of a bus topology?

    The main disadvantage of a bus topology is its susceptibility to single-point failures. If the central cable or backbone fails, the entire network goes down. Additionally, bus topologies can experience data collisions, which can slow down network performance.

  4. What type of topology is suitable for hierarchical networks?

    Tree topology is suitable for hierarchical networks, as it allows for a parent-child relationship between nodes. This hierarchical structure enables efficient routing of data and facilitates network management.

  5. What are the factors to consider when choosing a network topology?

    The factors to consider when choosing a network topology include the size and geographical distribution of the network, the required performance and bandwidth, the cost considerations, the security requirements, and the existing infrastructure.
