Question 57

The motherboard allocates resources and communicates with all other components.

The motherboard serves as the main circuit board in a computer, connecting and allowing communication between various hardware components. It manages data flow and resource allocation to ensure that all parts of the system work together effectively.

A) Expansion bus

The expansion bus is a subset of the motherboard that facilitates communication between the CPU and peripheral devices. While it plays a critical role in resource allocation for connected devices, it does not manage communication among all components, making it an incomplete answer.

B) System clock

The system clock regulates the timing of all computer operations, synchronizing the actions of the CPU and other components. However, it does not allocate resources or facilitate communication between the various hardware parts, which is essential for this question.

C) Motherboard

The motherboard is the central component that allocates resources and enables communication between the CPU, RAM, storage devices, and other peripherals. It acts as the backbone of the system, making it the correct answer to the question.

D) Hard drive

The hard drive is primarily responsible for data storage rather than resource allocation or communication among hardware components. Its role is limited to reading and writing data, which does not encompass the broader responsibilities required by the question.

Conclusion

The motherboard is definitively the correct answer because it serves as the core platform for resource management and inter-component communication in a computer system. In contrast, the other options either perform specific functions that do not encompass overall system management or are limited to particular tasks, failing to address the question comprehensively.
