2.4 Use of operating system tools user management, security policy, device management, performance monitor, task scheduler

            Operating system tools play a crucial role in managing various aspects of a computer system. Here's how some of these tools function:

1. User Management: This tool helps manage user accounts on a system. It is used to create new user accounts, delete existing ones, assign user roles, grant permissions, etc. It is critical for systems where multiple users need different access levels to system resources.
2. Security Policy: The security policy tool is used to manage system-wide security policies. This might include password requirements, account lockout policies, firewall settings, and more. It ensures that the system is secure and that only authorized users have access to the system resources.
3. Device Management: The device management tool is used to manage all the hardware devices connected to a system. It is used to install and update device drivers, configure devices, handle device conflicts, etc. It ensures that all devices are working correctly and efficiently.
4. Performance Monitor: The performance monitor tool is used to track system performance. It can monitor various aspects of the system like CPU usage, memory usage, network traffic, disk usage, etc. It helps in identifying system bottlenecks, underperforming components, and helps in system tuning.
5. Task Scheduler: The task scheduler tool is used to automate tasks. It is used to set up tasks to be run at specified times or under specified conditions. For example, a system administrator might schedule a backup operation to run every night or a software update check to run every week.

By using these tools effectively, system administrators can ensure that their systems are running efficiently, securely, and can effectively cater to the needs of their users.
