What is the primary role of diagnostics routines?

The primary role of diagnostics routines is to troubleshoot and check system performance. These routines are designed to identify potential issues within the system, monitor its performance, and provide information that can help users or technicians in resolving problems. They may assess hardware components, software status, and overall system health, allowing users to pinpoint where a failure might be occurring or to confirm that the system is operating efficiently.

Unlike options related to backing up data, enhancing graphics display, or managing user settings, which serve very different purposes, diagnostics specifically focus on the functional integrity of the system and are crucial for maintaining optimal operation and reliability.
