Question 6

All devices being connected to a single central device

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

A) Every device being connected to exactly two other devices

This option describes a linear bus or ring topology, where each device connects to two others, forming a continuous path. In a star topology, devices connect to a central hub, not to each other in a linear fashion.

B) Every device being connected to every other device

This option describes a fully connected mesh topology, where each device has direct links to all other devices. In contrast, a star topology relies on a single central device for communication rather than direct interconnections among all devices.

C) Devices being connected to a common communication line

This option describes a bus topology, where devices share a single communication line for data transmission. A star topology does not operate on a common line but rather through individual connections to a central hub.

D) All devices being connected to a single central device

This option correctly defines a star network topology. In this setup, each device connects independently to a central hub, allowing for easy addition and removal of devices without disrupting the network.

Conclusion

The correct answer, which highlights that all devices are connected to a single central device, distinctly defines a star network topology. The other options misrepresent the connections and structure of star networks, emphasizing the importance of the central hub in facilitating communication among devices.
