Understanding the Landscape
Before we compare, it’s important to define what we mean by “software platform.” At its core, a software platform refers to the underlying layer of software that provides the services and functionalities necessary for other software to operate. This typically includes:
- Operating System (OS): The core software that manages computer hardware and software resources and provides common services for computer programs.
- System Libraries: Collections of pre-written code that applications can use to perform common tasks.
- Runtime Environments: Software that executes bytecode or other intermediate representations of programs.
- Development Tools and Frameworks: Software used to create other software.
While there are numerous software platforms tailored for specific purposes (e.g., embedded systems, gaming consoles), this article will focus on the dominant general-purpose computing platforms for personal computers and servers.
