Final answer:
The network topology where all devices connect to one central device, such as a switch, is called star topology. It offers easy management but has a single point of failure in the central device.
Step-by-step explanation:
The physical network topology where all connected devices link to one central device, such as a switch, is known as the star topology.
In this configuration, each device on the network has a dedicated cable that runs to the central hub, switch, or router. This setup is common in many business and home networks because it allows for easy addition or removal of devices without disrupting the entire network. If the central device fails, however, the entire network goes down.
