What is the purpose of system monitoring tools?

System monitoring tools are designed primarily to analyze hardware performance and prevent failures. These tools continuously observe various system metrics, such as CPU usage, memory consumption, disk activity, and network traffic. By tracking these performance indicators, system monitoring tools help identify potential issues early, such as high resource usage that could lead to overheating or system crashes. This proactive approach allows administrators to take corrective actions before problems escalate, thereby maintaining system stability and performance.

While the other answer choices touch on aspects of computer functionality, they do not accurately reflect the core purpose of system monitoring tools. Enhancing graphics and sound quality pertains more to multimedia software or drivers, managing user accounts relates to administrative tools, and improving the operational lifespan of a device is more of an indirect benefit of monitoring rather than its primary function. The essence of system monitoring is focused on real-time performance analysis to ensure smooth and efficient operation of hardware components.
