What is described by a single bus configuration?

A single bus configuration refers to a system where all circuits are interconnected to a centralized main bus. This setup means that every component or circuit passes through this central bus for connections. This type of configuration facilitates a straightforward design, making it simple to add or remove circuits as needed. However, it can also make the system less reliable because if the main bus fails, the entire system can be compromised.

In contrast, redundant systems would involve multiple buses to provide failover capacity, independent circuits would not share a connection but operate separately, and dual power sources would imply a design for increased power reliability, none of which aligns with the definition of a single bus configuration.
