Application software is software that is intended for end-user use – not operating, administering or programming a computer. An application (app, application program, software application) is any program that can be categorized as application software. Application is a subjective classification that is often used to differentiate from system and utility software.

The abbreviation app became popular with the 2008 introduction of the iOS App Store, to refer to applications for mobile devices such as smartphones and tablets. Later, with the release of the Mac App Store in 2010 and the Windows Store in 2011, it began to be used to refer to end-user software in general, regardless of platform.

Mozilla Firefox, or simply Firefox, is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. It uses the Gecko rendering engine to display web pages, which implements current and anticipated web standards. Firefox is available for Windows 10 or later versions of Windows, macOS, and Linux. Its unofficial ports are available for various Unix and Unix-like operating systems, including FreeBSD, OpenBSD, NetBSD, and other operating systems, such as ReactOS. It is the default, pre-installed browser on Debian, Ubuntu, and other Linux distros. Firefox is also available for Android and iOS. However, as with all other iOS web browsers, the iOS version uses the WebKit layout engine instead of Gecko due to platform requirements. An optimized version was also available on the Amazon Fire TV as one of the two main browsers available with Amazon's Silk Browser, until April 30, 2021, when Firefox would be discontinued on that platform. Firefox is the spiritual successor of Netscape Navigator, as the Mozilla community was created by Netscape in 1998, before its acquisition by AOL. Firefox was created in 2002 under the codename "Phoenix" by members of the Mozilla community who desired a standalone browser rather than the Mozilla Application Suite bundle. During its beta phase, it proved to be popular with its testers and was praised for its speed, security, and add-ons compared to Microsoft's then-dominant Internet Explorer 6. It was released on November 9, 2004, and challenged Internet Explorer's dominance with 60 million downloads within nine months. In November 2017, Firefox began incorporating new technology under the code name "Quantum" to promote parallelism and a more intuitive user interface.

Firefox usage share grew to a peak of 32.21% in November 2009, with Firefox 3.5 overtaking Internet Explorer 7, although not all versions of Internet Explorer as a whole; its usage then declined in competition with Google Chrome. As of February 2025, according to StatCounter, it had a 6.36% usage share on traditional PCs (i.e. as a desktop browser), making it the fourth-most popular PC web browser after Google Chrome (65%), Microsoft Edge (14%), and Safari (8.65%).

OpenBSD is a security-focused, free software, Unix-like operating system based on the Berkeley Software Distribution (BSD). Theo de Raadt created OpenBSD in 1995 by forking NetBSD 1.0. The OpenBSD project emphasizes portability, standardization, correctness, proactive security, and integrated cryptography.

The OpenBSD project maintains portable versions of many subsystems as packages for other operating systems. Because of the project's preferred BSD license, which allows binary redistributions without the source code, many components are reused in proprietary and corporate-sponsored software projects. The firewall code in Apple's macOS is based on OpenBSD's PF firewall code, Android's Bionic C standard library is based on OpenBSD code, LLVM uses OpenBSD's regular expression library, and Windows 10 uses OpenSSH (OpenBSD Secure Shell) with LibreSSL.

Microsoft Edge is a proprietary cross-platform web browser created by Microsoft and based on the Chromium open-source project, superseding Edge Legacy. In Windows 11, Edge is the only browser available from Microsoft. However, a bypass is available to open Internet Explorer.

First made available only for Android and iOS in 2017, in late 2018, Microsoft announced it would completely rebuild Edge as a Chromium-based browser with Blink and V8 engines, which allowed the browser to be ported from Windows 10 to macOS. The new Edge was publicly released in January 2020, and on Xbox as well as Linux in 2021. Edge was also available on Windows 7 and 8/8.1 until early 2023.

The Xbox One is a home video game console developed by Microsoft. Announced in May 2013, it is the successor to Xbox 360 and the third console in the Xbox series. It was first released in North America, parts of Europe, Australia, and South America in November 2013 and in Japan, China, and other European countries in September 2014. It is the first Xbox game console to be released in China, specifically in the Shanghai Free-Trade Zone. Microsoft marketed the device as an "all-in-one entertainment system", hence the name "Xbox One". An eighth-generation console, it mainly competed against Sony's PlayStation 4 and Nintendo's Wii U and later the Nintendo Switch.

Moving away from its predecessor's PowerPC-based architecture, the Xbox One marks a shift back to the x86 architecture used in the original Xbox; it features an Accelerated Processing Unit (APU) from AMD built around the x86-64 instruction set. Xbox One's controller was redesigned over the Xbox 360's, with a redesigned body, D-pad, and triggers capable of delivering directional haptic feedback. The console places an increased emphasis on cloud computing, as well as social networking features and the ability to record and share video clips or screenshots from gameplay or livestream directly to streaming services such as Mixer and Twitch. Games can also be played off-console via a local area network on supported Windows 10 devices. The console can play Blu-ray Disc, and overlay live television programming from an existing set-top box or a digital tuner for digital terrestrial television with an enhanced program guide. The console optionally included a redesigned Kinect sensor, marketed as the "Kinect 2.0", providing improved motion tracking and voice recognition.

The Adlam script is a script used to write Fulani. The name Adlam is an acronym derived from the first four letters of the alphabet (A, D, L, M), standing for Alkule Dandayɗe Leñol Mulugol (𞤀𞤤𞤳𞤵𞤤𞤫 𞤁𞤢𞤲𞤣𞤢𞤴𞤯𞤫 𞤂𞤫𞤻𞤮𞤤 𞤃𞤵𞤤𞤵𞤺𞤮𞤤), which means "the alphabet that protects the peoples from vanishing". It is one of many indigenous scripts developed for specific languages in West Africa.

Adlam is supported in Google's Android and Chrome operating systems. There are also Android apps to send SMS in Adlam and to learn the alphabet. On computers running Microsoft Windows, the Adlam script received native support beginning with Windows 10 version 1903, which was released in May 2019. On macOS, the Adlam script received support beginning with Ventura in 2022.

Candy Crush Saga is a free-to-play tile-matching video game released by King on April 12, 2012, originally for Facebook; other versions for iOS, Android, Windows Phone, and Windows 10 followed. It is a variation of their browser game Candy Crush.

In the game, players complete levels by swapping colored pieces of candy on a game board to make a match of three or more of the same color, eliminating those candies from the board and replacing them with new ones, which could potentially create further matches. Matches of four or more candies create unique candies that act as power-ups with larger board-clearing abilities. Boards have various goals that must be completed within a fixed number of moves, such as collecting a specific number of a type of candy.

Media Player (also known as Windows Media Player in the Microsoft Store) is a media player software for Windows, developed by Microsoft.

In computing, a file shortcut is a handle in a user interface that allows the user to find a file or resource located in a different directory or folder from the place where the shortcut is located. Similarly, an Internet shortcut allows the user to open a page, file or resource located at a remote Internet location or Web site.

Shortcuts are typically implemented as a small file containing a target URI or GUID to an object, or the name of a target program file that the shortcut represents. The shortcut might additionally specify parameters to be passed to the target program when it is run. Each shortcut can have its own icon. Shortcuts are very commonly placed on a desktop, in an application launcher panel such as the Microsoft Windows Start menu, or in the main menu of a desktop environment. The functional equivalent in the Macintosh operating system is called an alias. Unix-like systems have symbolic links which point to a target file, and often support .desktop files which provide additional configuration details.

A terminal emulator, or terminal application, is a computer program that emulates a video terminal within another display architecture. Though typically synonymous with a shell or text terminal, the term terminal covers all remote terminals, including graphical interfaces. A terminal emulator inside a graphical user interface is often called a terminal window.

A terminal window allows the user access to a text terminal and all its applications such as command-line interfaces (CLI) and text user interface (TUI) applications. These may be running either on the same machine or on a different one via telnet, ssh, dial-up, or over a direct serial connection. On Unix-like operating systems, it is common to have one or more terminal windows connected to the local machine.

PowerShell is a shell program developed by Microsoft for task automation and configuration management. As is typical for a shell, it provides a command-line interpreter for interactive use and a script interpreter for automation via a language defined for it. Originally only for Windows, known as Windows PowerShell, it was made open-source and cross-platform on August 18, 2016, with the introduction of PowerShell Core. The former is built on the .NET Framework and the latter on .NET (previously .NET Core).

PowerShell is bundled with current versions of Windows and can be installed on macOS and Linux. Since Windows 10 build 14971, PowerShell replaced Command Prompt as the default command shell exposed by File Explorer.

Windows 10 is a major release of the Windows NT operating system developed by Microsoft. Microsoft described Windows 10 as an "operating system as a service" that would receive ongoing updates to its features and functionality, augmented with the ability for enterprise environments to receive non-critical updates at a slower pace or use long-term support milestones that will only receive critical updates, such as security patches, over their five-year lifespan of mainstream support. It was released on 29 July 2015.

Groove Music is a discontinued audio player software application and associated music streaming service from Microsoft. Originally known as Xbox Music before rebranding to Groove Music in 2015, the app was included with Windows 8, Windows 8.1 and Windows 10 (as well as very early builds of Windows 11).

The music streaming service, which was called Groove Music Pass, was supported across Windows, Xbox video game consoles, Windows Phone, as well as Android and iOS. As of 2014, the Groove catalogue had over 50 million tracks. Its subscription service Groove Music Pass was officially discontinued on December 31, 2017, and the Android and iOS versions of the Groove Music app were discontinued in December 2018, restricting the player to its native Microsoft Store base.
