What is another term for the system bus in a computer?

• A. host bus
• B. data bus
• C. address bus
• D. control bus

Answer: (A)

The correct response refers to the system bus as the "host bus," which is often viewed as the main bus that connects the various components of a computer, such as the CPU, memory, and input/output devices. The term "host bus" emphasizes the bus's role in connecting the primary components of the computer system, allowing them to communicate with each other effectively. The other terms mentioned in the choices focus on specific functionalities within the bus architecture. The "data bus" is specifically responsible for transferring actual data between components, while the "address bus" is used to determine the addresses of where data should be sent or retrieved from memory. The "control bus" carries control signals from the CPU to other components, managing and coordinating the operations of the system. Each of these components plays a crucial role in the architecture of a computer, but when referring to the system bus as a whole, "host bus" is commonly used.
