Final answer:
In a large network, switches are connected together in a star topology.
Step-by-step explanation:
In a large network, when several switches need to be connected together, one device is placed at the center forming a star. The star topology is a common network configuration where all devices are connected to a central device, usually a switch. This central device acts as a hub, enabling communication between all the connected devices. The star topology offers benefits such as easy scalability, centralized management, and fault isolation.
