Which topology connects devices in a star configuration?

The correct answer is the star topology, which connects devices in a star configuration. In a star topology, all devices, or nodes, are connected to a central hub or switch. This central device acts as a repeater for data transmissions, effectively managing the flow of information between the connected devices.

The star configuration is beneficial because if one of the connecting devices fails, it does not impact the entire network, allowing for easier troubleshooting and maintenance. The centralized hub or switch also allows for efficient data management and traffic control, making it a popular choice in local area networks (LANs).

In contrast, the bus topology connects all devices along a single communication line (the "bus"), which can lead to performance issues if many devices are active simultaneously. Mesh topology connects devices in a manner where multiple paths are present between devices, offering redundancy and reliability but also increasing complexity. A tree topology combines characteristics of star and bus topologies, forming a hierarchical structure, which may not represent a straightforward star configuration. Each topology has its advantages and use cases, but for a star configuration specifically, the star topology is the correct choice.
