Question 12

All devices being connected to a single central device

A star network topology is characterized by all devices being connected to a single central device, such as a hub or switch, which facilitates communication between the devices.

A) Every device being connected to exactly two other devices

This option describes a linear or ring topology rather than a star topology. In a star network, devices do not connect to exactly two other devices; instead, they connect individually to a central hub.

B) Devices being connected to a common communication line

This describes a bus topology, where devices share a single communication line. In a star topology, each device has its own connection to the central device, distinguishing it from a common line setup.

C) Every device being connected to every other device

This option represents a mesh topology, where each device has a direct connection to every other device. A star topology does not require such direct connections; rather, all communications pass through the central device.

D) All devices being connected to a single central device

This accurately defines a star network topology. In this configuration, all devices communicate through one central point, making it easy to manage and troubleshoot the network.

Conclusion

The correct answer, D, precisely describes the defining feature of a star network topology, distinguishing it from other network types like bus, ring, or mesh. Options A, B, and C illustrate different topologies, confirming that they do not apply to the question regarding star networks.
