Pöytätietokoneohjelma

Pöytätietokoneohjelma, or desktop application, refers to a software program designed to run on a personal computer or workstation. Unlike web applications that run in a web browser or mobile applications designed for smartphones and tablets, desktop programs are installed directly onto the operating system of a desktop or laptop computer. They typically leverage the full capabilities of the hardware, including processing power, memory, and local storage, to perform complex tasks.

The functionality of desktop applications is vast, ranging from word processing and spreadsheet software to advanced graphic design tools, video editing suites, and complex scientific simulations. They can operate offline, meaning they do not require a constant internet connection to function, although many modern desktop applications incorporate online features for updates, cloud storage, or collaboration. Installation usually involves downloading an installer file and following a guided setup process. Once installed, the program can be launched from the operating system's application menu or desktop shortcuts.

The user interface of a desktop program is typically designed for interaction with a keyboard and mouse, offering features like windows, menus, toolbars, and dialog boxes. While the dominance of web and mobile applications has grown, desktop programs remain crucial for many professional and specialized tasks due to their performance, offline capabilities, and deep integration with the underlying operating system. Examples include Microsoft Word, Adobe Photoshop, and the operating system's file explorer.
