What functionality does the task manager provide in an operating system?

The task manager is a crucial tool within an operating system that allows users to view and manage running processes and applications. This functionality includes providing a comprehensive list of all active processes, indicating which applications are currently running, and displaying performance metrics such as CPU and memory usage. Users can also use the task manager to end unresponsive applications or processes, which is essential for maintaining system stability and performance.

While other functionalities such as managing user accounts and permissions or monitoring network activity are important for operating systems, they fall outside the primary role of the task manager. The task manager focuses specifically on process management, enabling users to actively control and monitor the system's performance in real-time. This capability is fundamental for troubleshooting and optimizing system operation, making it an invaluable tool for both casual users and advanced administrators.
