Which type of network topology entirely shuts down if there is a break in the main cable?

In a star topology, all devices are connected to a central hub or switch. If one cable fails, only the device connected by that cable is affected, while the rest of the network continues to function normally. This design enhances reliability and reduces the impact of a single point of failure.

In a ring topology, each device is connected to two other devices, forming a circular pathway for data. If one connection fails, the data can still travel in the opposite direction, allowing the network to remain operational. Therefore, while a break in a single connection can disrupt communication, it does not necessarily shut down the entire network.

Wireless networks utilize radio waves to connect devices without physical cabling. If one device fails or experiences connectivity issues, it does not impact the entire network, as other devices can still communicate. Wireless networks are inherently more robust against single points of failure compared to wired topologies like bus.
