Systems Software
In addition to the core files that make up the operating system, there are a number of files and programs that are considered "part" of the operating system. These include software libraries of functions, system services, printer drivers, and other hardware, system preferences and configuration files-and much more.

In contrast to applications, users have less choice as to what parts of the systems software should be installed. In general, systems software act as the first line of communication between the hardware and the software.
