What type of network topology is described by a hub in the center with nodes around it?

The type of network topology characterized by a hub in the center with nodes arranged around it is known as the star topology. In this configuration, all peripheral nodes (such as computers or devices) are directly connected to a central hub or switch. The hub acts as a repeater for data flowing to and from the nodes, enabling straightforward communication between them.

One of the primary advantages of the star topology is its ease of installation and maintenance; if one connection fails, it does not affect the rest of the network. This setup also facilitates easy troubleshooting, as individual connections can be tested without disrupting the overall network. Additionally, star topologies can be easily expanded by adding more nodes, as they only require an additional connection to the hub.

In contrast, the bus topology utilizes a single central cable to which all nodes are connected, leading to potential issues if that cable fails. The ring topology arranges nodes in a closed loop, where each node is connected to two others, creating a pathway for data in one direction or the other. The mesh topology, on the other hand, involves each node connecting to multiple other nodes, enhancing redundancy and reliability but increasing complexity and installation difficulty. Thus, the star topology stands out for its hub-and-spoke structure,
