A utility program is a type of software designed to help manage and tune computer hardware, operating system, or application software by performing a specific set of tasks aimed at maintaining or enhancing the computer's functionality.
Let's analyze the provided options:
A disk defragmenter - This is a classic example of a utility program. It reorganizes the data on a hard drive so that related pieces of data are grouped together, which can help improve the access speed and efficiency of the system.
Microsoft Word - This is a word processor used for creating text documents. It is not considered a utility program because it is designed mainly for content creation rather than system maintenance.
Mozilla Firefox - This is a web browser that allows users to access the internet. It falls under application software rather than utility software, as its primary function is browsing and not system optimization.
Adobe Photoshop - This is an image editing application used for creating and modifying images. Like Microsoft Word and Mozilla Firefox, it is application software, not a utility program.
Therefore, the correct answer to the question is A. A disk defragmenter . This program helps manage and optimize how data is stored and accessed on a computer's hard drive, making it a suitable example of a utility program.
Utility programs are essential for ensuring that computer systems run smoothly, efficiently, and safely by performing supportive and functional tasks like virus scanning, data backup, and, as mentioned, disk defragmentation.
