Which network topology is characterized by a central hub connecting all devices?

The star topology is characterized by a central hub or switch that connects all devices in the network. In this configuration, each device has a dedicated point-to-point connection to the hub, creating a star-like structure. The central hub acts as a conduit for data transmission, making it straightforward for devices to communicate with one another by sending data through the hub.

This design provides several advantages, such as ease of installation and configuration, as well as simplified troubleshooting. If one connection or device fails, it does not affect the rest of the network, making it a robust choice for many networking scenarios. This centralized design also facilitates the addition or removal of devices without disrupting the entire network.

In contrast, other topologies do not utilize a central point of connection. The mesh topology connects each device to every other device, allowing for numerous paths for data to travel but requiring extensive cabling and configuration. The bus topology uses a single cable (the bus) to which all devices are connected, making it less reliable because if the main cable fails, the entire network goes down. The ring topology connects devices in a circular fashion where each device is connected to two others, and data travels in one direction around the ring. If one device or connection fails, it can disrupt communication
