Which network topology uses a central device to connect directly to all other devices?

The star network topology is characterized by having a central device, often referred to as a hub or switch, that connects directly to all other devices in the network. This design allows for easy management and troubleshooting since all data passes through the central device, making it simple to isolate and resolve issues. Additionally, if one connection fails, it does not affect the other devices on the network, improving reliability.

In contrast, a ring network connects each device to two other devices forming a circular pathway for data. In a mesh network, multiple connections exist between devices, allowing for multiple paths for data transmission, which can enhance resilience but complicates the structure. A bus network utilizes a single central cable (the bus) to which all devices are directly connected, but if that cable fails, the entire network is affected. Therefore, the star topology stands out for its structured approach and ease of use.
