This document discusses different categories of application software. It identifies four main categories: packaged software which meets the needs of many users; custom software which is tailored to a specific business; web applications which can be accessed online; and open source software which can be freely modified and distributed. It also discusses other types like shareware, freeware, and public domain software and explains their basic definitions. Finally, it briefly discusses the role of system software in interfacing between users, applications, and computer hardware.

12. The Role of System Software
serves as the interface between the user, the application software,
and the computer’s hardware.
 it coordinates all the activities of the computer.
includes starting application software and transferring data among
input and output devices and memory.
To use application software, such as a word processing program,
your computer must be running system software — specifically, an
operating system.
