What type of topology does a hub commonly create?

A hub commonly creates a star topology. In a star topology, all network devices are connected to a central hub or switch. This configuration allows for easy addition and removal of devices without disrupting the overall network. Since each device has a dedicated connection to the hub, if one connection fails, it does not affect the rest of the network, enhancing reliability and troubleshooting.

Hubs function merely as a connection point, allowing data to be transmitted to all devices on the network segment. Therefore, the star configuration is prevalent where hubs and switches are used, making it a practical choice for many local area networks (LANs).

In contrast, mesh, ring, and bus topologies have different structural characteristics and implications for network performance and data transmission, which do not involve the use of a hub in the same central manner as star topology does.
