tværplatformkørsel

Tværplatformkørsel, sometimes translated as cross-platform execution or multi-platform compatibility, refers to the ability of software, code, or a system to function correctly on multiple different operating systems or hardware architectures without requiring significant modifications. This concept is crucial in modern software development, enabling broader reach and reducing development overhead.

Achieving tværplatformkørsel often involves using programming languages with built-in support for abstraction layers or employing specialized tools and frameworks. Languages like Java, which compile to bytecode executed on a virtual machine (JVM), are a prime example. The JVM itself is implemented for various platforms, allowing Java applications to run anywhere a JVM is available. Similarly, web technologies like HTML, CSS, and JavaScript are inherently cross-platform, as they are interpreted by web browsers that exist on virtually all operating systems.

Other approaches include compiling source code separately for each target platform, a process common with languages like C or C++, or utilizing cross-compilers. Frameworks such as .NET Core (now .NET) and React Native facilitate the creation of applications that can run on Windows, macOS, Linux, iOS, and Android from a single codebase. The benefits of tværplatformkørsel include faster development cycles, reduced maintenance costs, and the ability to reach a wider audience of users regardless of their preferred operating system.
