Which description best fits a computer bus?

### Why this is right A bus is a communication pathway used to carry information or signals between computer components. ### The concept A computer's components must exchange information to work together. Buses provide pathways for that communication. They should not be confused with programs, display devices, or storage media, which perform different functions. ### The other options - **B. A device that permanently displays images**: This is not the role of a bus; a monitor presents visual output. - **C. A program that assigns drive letters**: This describes software-related drive management, not a hardware communication path. - **D. A storage medium that can be rewritten**: This describes rewritable storage media, not a bus. ### Terms - **Storage medium**: A physical or electronic means of retaining data. ### Remember A bus is a route for communication between components.
