Describe the functions of system software.

System software is a type of software that is designed to facilitate the operation of computer hardware and provide a platform for running application software. It consists of several programs that perform various functions to ensure the smooth operation of a computer system. The main functions of system software include:

1. Operating System (OS) Management:

• The most critical function of system software is to manage the computer's hardware and provide a platform for running applications.
• It manages the allocation of resources such as memory, CPU, and storage to different processes and ensures their efficient use.

2. Memory Management:

• System software manages the computer's memory, including RAM and virtual memory.
• It allocates memory to different processes and ensures that they do not interfere with each other's memory space.

3. File Management:

• System software provides functions for creating, deleting, and managing files and directories.
• It manages the storage of files on disk drives and ensures their efficient retrieval and storage.

4. Device Management:

• System software manages the computer's input and output devices, such as keyboards, mice, printers, and monitors.
• It handles the communication between the computer and these devices, ensuring that they function correctly.

5. Security:

• System software provides security features to protect the computer system from unauthorized access and malicious software.
• It includes functions such as user authentication, access control, and encryption to ensure the confidentiality and integrity of data.

6. System Performance Monitoring:

• System software monitors the performance of the computer system, including CPU usage, memory usage, and disk usage.
• It provides tools for diagnosing and troubleshooting performance issues to optimize system performance.

7. System Configuration:

• System software allows users to configure various system settings, such as network settings, display settings, and power management settings.
• It provides a user-friendly interface for changing these settings and customizing the system to meet the user's needs.

8. System Recovery:

• System software provides tools for recovering the system in case of a system failure or error.
• It includes features such as system restore, backup, and recovery tools to ensure that the system can be restored to a functional state.

In summary, system software plays a crucial role in managing and controlling the hardware and software components of a computer system. It provides a platform for running application software and ensures the efficient operation of the computer system.
