Final answer:

Operating systems manage hardware resources and aid in various activities. User interfaces vary between graphical and command-line interfaces. Virtual memory extends RAM, utility programs maintain systems, programs fall into categories, and word processing has various features.


Explanation:

Operating systems are software that manage and allocate hardware resources. Five activities aided by an operating system are resource allocation, process management, memory management, file management, and user interface.

User interface is how users interact with the computer. A graphical user interface (GUI) uses graphical elements, icons, and windows, while a command-line interface (CLI) requires commands to be typed in text form.

Virtual memory expands computer memory by using disk space as an extension. A computer uses it when physical memory (RAM) is full to swap data back and forth from RAM to disk.

A utility program is software for maintenance or optimization. Two examples are antivirus software and disk cleanup tools.

The categories of programs and applications include system software, programming software, application software, proprietary software, and open-source software.

Additional features of word processing include spell check, tables, graphs, formatting tools, and collaboration tools.
