Word processors, spreadsheets, database programs, graphics tools, and presentation software all share one feature: each is designed to let a user perform a specific, everyday task such as writing documents, calculating figures, storing records, drawing, or building slides. Software written to carry out these end-user tasks is grouped together as application packages.
Utility packages instead perform maintenance tasks such as compression, backup, or disk cleanup rather than direct user tasks. Operating system software manages the computer's hardware and resources and provides the platform on which application packages run; it is not itself a tool for writing, calculating, or presenting.
Exam takeaway: if a list of software items describes what an ordinary user directly works with to produce documents, numbers, images, or slides, it belongs to application packages, not utility or operating system software.
