Which topology connects all devices to a central hub?

The topology that connects all devices to a central hub is the star topology. In a star configuration, all peripheral devices, such as computers and printers, are directly connected to a central hub or switch. This structure allows for easy management and troubleshooting since any failure in a single connection does not disrupt the entire network; only the device connected through that specific link would be affected.

Additionally, the central hub can manage data traffic, allowing for efficient communication between devices. Because of its straightforward layout and ease of installation, star topology is commonly used in local area networks (LANs). The other topologies, while effective in their own contexts, do not utilize a central hub to connect devices in the same way that star topology does.
