What is a bus network in computing?

A bus network in computing is characterized by the fact that multiple devices are connected along a single communication line, known as the bus. This configuration allows all connected devices to share the same transmission medium, facilitating communication with one another without requiring a dedicated connection for each device. In this setup, data sent from one device travels along the bus and can be received by all other devices connected to it, enabling effective and simple communication within the network.

The design of a bus network is efficient for small networks as it minimizes the amount of cabling required and tends to be cost-effective. However, this system can be susceptible to collisions, especially when multiple devices attempt to communicate simultaneously, as all devices share the same bandwidth.

In contrast, options suggesting multiple lines or devices managed separately do not accurately represent a bus network. The choices regarding network traffic management or security methods are also unrelated to the basic definition of a bus network and its intended functionality.
