Why are utility programs essential for a computer system?

Utility programs are essential for a computer system because they conduct regular maintenance and repair tasks that help ensure the smooth operation and longevity of the system. These programs perform functions such as disk cleanup, error checking, virus scanning, and data recovery, which maintain system performance and address potential issues proactively. By providing tools for system optimization and troubleshooting, utility programs play a critical role in sustaining the overall health of computer systems and avoiding malfunctions that could lead to data loss or hardware failure.

In contrast, while installing applications, enhancing graphics, and improving gaming performance are important aspects of a computer's functionality, these tasks are typically carried out by application software or graphics drivers rather than utility programs. Utility programs primarily focus on maintenance rather than direct application use or enhancements in specific areas like graphics or gaming performance.
