Question 61

The hardware component that consists of wires and protocols for moving information among internal and peripheral components is the expansion bus.

The expansion bus serves as a communication pathway that allows various internal and peripheral components to exchange data efficiently. It comprises a set of wires and protocols that facilitate this transfer of information.

A) Motherboard

The motherboard is the main circuit board that houses the CPU, RAM, and other essential components of a computer. While it includes the expansion bus as part of its architecture, it is not solely responsible for the movement of information; rather, it integrates various components, including the bus itself.

B) Hard drive

The hard drive is a storage device used to save and retrieve digital information. It does not consist of wires or protocols for moving information among components; instead, it serves as a destination for data storage, making it irrelevant to the question about data movement.

C) Expansion bus

The expansion bus is specifically designed to facilitate communication between the internal components of a computer and peripheral devices. It consists of the necessary wires and protocols that allow data to be transferred, making it the correct answer to the question.

D) System clock

The system clock is a timing device that synchronizes the operations of a computer's components. While it plays a critical role in coordinating data transfers, it does not consist of wires and protocols for moving information, thus making it incorrect in this context.

Conclusion

The expansion bus is definitively the correct answer as it directly addresses the hardware component responsible for moving information among internal and peripheral components. Other options, such as the motherboard and hard drive, serve different functions and do not specifically pertain to the movement of data, while the system clock is focused on timing rather than data transfer itself.
