What describes a network topology where devices connect to a shared communication line?

In network topology, the term that best describes a configuration where all devices are connected to a single, shared communication line is bus topology. In this arrangement, all nodes (devices) are connected through a central cable, known as the bus. Data packets travel along this bus, and all connected devices receive the packets, although only the intended recipient processes the information. This setup is straightforward and cost-effective, particularly for small networks.

Bus topology is known for its simplicity and ease of setup, making it suitable for scenarios where cost is a critical factor. However, it also has limitations, such as difficulties in troubleshooting and potential performance issues as more devices are added to the network. If the bus cable encounters a failure, the entire network can be affected, highlighting the key weaknesses of this topology compared to others that might have more robust designs.
