Which topology involves running cables from each node to connect at a central device, typically a hub?

Star topology is characterized by its structure of connecting each node directly to a central device, commonly referred to as a hub or switch. This central device acts as a mediator for data transmission among the nodes, allowing for efficient communication.

The star topology offers several advantages, such as ease of installation and troubleshooting; if one connection fails, it does not impact the entire network, only the specific node that is affected. Additionally, adding or removing nodes can be done without disrupting the overall network.

In comparison to other topologies, such as bus, ring, and tree, star topology provides a more robust and flexible approach to network design, making it a preferred choice in many modern networking scenarios. The bus topology, for instance, relies on a single central cable, making it more susceptible to failure. Ring topology connects nodes in a circular manner, which can lead to complete failure if any one connection is broken. Tree topology is a variation that combines characteristics of star and bus topologies but still centers around a hierarchical structure which can complicate connections.
