Which of the following can be monitored by the Task Manager?

The ability to monitor real-time CPU usage is a fundamental feature of the Task Manager. It provides a detailed view of the current utilization of the CPU by various processes and the overall percentage of CPU being used. This information is crucial for users and administrators to diagnose performance issues, understand how applications are consuming system resources, and monitor the health of the system.

In contrast, while the Task Manager does provide insights into system performance, it does not specifically monitor Internet connection speed, user permissions, or file system errors. Internet connection speed is typically monitored through network management tools or software. User permissions are managed through operating system settings, not monitored in real-time via the Task Manager. File system errors can be detected through system diagnostics or specific tools, rather than in the Task Manager interface. Thus, real-time CPU usage being monitored directly in the Task Manager highlights its critical role in system management and performance monitoring.
