CPSI is helping you deliver the type of healthcare you want. It's care that is about more than one specific care setting, service or platform. It's the kind of care that's building a new model for trusted connections in our communities for today and tomorrow.
Operating system software. An operating system (OS) is a set of programs that manage computer hardware resources and provide common services for application software.

System software is software designed to provide a platform for other software.^[1] Examples of system software include operating systems like macOS, Ubuntu (a Linux distribution) and Microsoft Windows, computational science software, game engines, industrial automation, and software as a service applications.^[2]

In contrast to system software, software that allow users to do user-oriented tasks such as create text documents, play games, listen to music, or browse the web are collectively referred to as application software.^[3]

In the early days of computing^[when?] most application software was custom-written by computer users to fit their specific hardware and requirements. In contrast, system software was usually supplied by the manufacturer of the computer hardware and was intended to be used by most or all users of that system.

The line where the distinction should be drawn is not always clear.^{[according to whom?]} Many operating systems bundle^[jargon] application software. Such software is not considered system software when it can be uninstalled usually without affecting the functioning of other software. Exceptions could be e.g. web browsers such as Internet Explorer where Microsoft argued in court that it was system software that could not be uninstalled. Later examples are Chrome OS and Firefox OS where the browser functions as the only user interface and the only way to run programs (and other web browsers can not be installed in their place), then they can well be argued to be (part of) the operating system and hence system software.

Another borderline example is cloud-based software. This software provides services to a software client (usually a web browser or a JavaScript application running in the web browser), not to the user directly, and is therefore systems software. It is also developed using system programming methodologies and systems programming languages. Yet from the perspective of functionality there is little difference between a word processing application and word processing web application.

Operating systems or system control programs[edit]

The operating system (prominent examples being Microsoft Windows, macOS, Linux, and z/OS), allows the parts of a computer to work together by performing tasks like transferring data between memory and disks or rendering output onto a display device. It provides a platform (hardware abstraction layer) to run high-level system software and application software.

A kernel is the core part of the operating system that defines an API for applications programs (including some system software) and an interface to device drivers.

Device drivers, including also computer BIOS and device firmware, provide basic functionality to operate and control the hardware connected to or built into the computer.

A user interface 'allows users to interact with a computer.'^[4] Either a command-line interface (CLI) or, since the 1980s a graphical user interface (GUI). Since this is the part of the operating system the user directly interacts with, it may be considered an application and therefore not system software.

Utility software or system support programs[edit]

For historical reasons, some organizations use the term systems programmer to describe a job function which is more accurately termed systems administrator. Software tools these employees use are then called system software. This so-called Utility software helps to analyze, configure, optimize and maintain the computer, such as virus protection. In some publications, the term system software also includes software development tools (like a compiler, linker or debugger).^[5]
