Utility software performs the maintenance work of a computer.

Utility software is a type of software that is designed to perform specific tasks to enhance the functionality and performance of a computer system. It includes a variety of tools and programs that help in maintaining and optimizing the computer.

Functions of utility software:

1. System optimization: Utility software helps in optimizing the performance of a computer by cleaning up unnecessary files, defragmenting the hard drive, and removing temporary files. This improves the speed and efficiency of the system.

2. Security: Utility software provides tools to protect the computer from viruses, malware, and other online threats. It includes antivirus programs, firewalls, and spyware removal tools.

3. Backup and recovery: Utility software allows users to create backups of important files and folders, ensuring that data is not lost in case of system failure or accidental deletion. It also provides tools for recovering lost or deleted files.

4. Disk management: Utility software helps in managing the disk space on a computer. It allows users to partition the hard drive, format disks, and manage disk partitions. This helps in organizing data and improving storage efficiency.

5. Hardware diagnostics: Utility software includes tools for diagnosing and troubleshooting hardware issues. It can perform tests to check the health and performance of hardware components such as the hard drive, RAM, and processor.

6. Data recovery: Utility software can recover lost or deleted data from storage devices such as hard drives, memory cards, and USB drives. It can scan the device and retrieve the lost data, even if it has been accidentally deleted or formatted.

Examples of utility software:

- Antivirus software (e.g., Norton, McAfee)
- Disk cleanup tools (e.g., CCleaner)
- Disk defragmentation tools (e.g., Defraggler)
- Backup and recovery software (e.g., Acronis True Image, EaseUS Todo Backup)
- System optimization tools (e.g., Advanced SystemCare, Glary Utilities)
- Data recovery software (e.g., Recuva, Stellar Data Recovery)

In conclusion, utility software plays a crucial role in maintaining and optimizing a computer system. It performs various tasks such as system optimization, security, backup and recovery, disk management, hardware diagnostics, and data recovery.
