System software is a platform comprised of Operating System (OS) programs and services, including settings and preferences, file libraries and functions used for system applications. System software also includes device drivers that run basic computer hardware and peripherals.

From my perspective, the system software is that code that is required to enable the applications programs to execute. In many O/S variants, there is a distinction of user-state and supervisor-state within the processor. Things that live in user-state are applications, libraries.
System software is software designed to provide a platform for other software. 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.
System software is software on a computer that is designed to control and work with computer hardware. The two main types of system software are the operating system and the software installed with the operating system, often called utility software. In some cases, the operating system and utility software depend on each other to function properly.
Mar 01, 2019 System software is a type of computer program that is designed to run a computer’s hardware and application programs. If we think of the computer system as a layered model, the system software is the interface between the hardware and user applications. The operating system is the best-known example of system software. The OS manages all the other programs in a computer.
System software refers to the files and programs that make up your computer's operating system. System files include libraries of functions, system services, drivers for printers and other hardware, system preferences, and other configuration files.

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 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]/cyberlink-dvd-suite-deluxe-free.html. 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]
