For example, in a single computer system, this would be the computer's architecture, operating system (OS), and runtime libraries. [2] In the case of an application program or a computer video game , the most relevant layer is the operating system, so it can be called a platform itself (hence the term cross-platform for software that can be ...
An instruction set architecture (ISA) is an abstract model of a computer, also referred to as computer architecture.A realization of an ISA is called an implementation.An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between software and hardware.
In 2008, the Department of Management Science and Technology in the Athens University of Economics and Business published an analysis of the FreeBSD, Linux, Solaris, and Windows operating system kernels which looked for differences between code developed using open-source and proprietary processes. The study collected metrics in the areas of ...
In computing, cross-platform software (also called multi-platform software, platform-agnostic software, or platform-independent software) is computer software that is designed to work in several computing platforms. [1] Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without ...

In software engineering, porting is the process of adapting software for the purpose of achieving some form of execution in a computing environment that is different from the one that a given program (meant for such execution) was originally designed for (e.g., different CPU, operating system, or third party library).
Hardware virtualization (or platform virtualization) pools computing resources across one or more virtual machines. A virtual machine implements functionality of a (physical) computer with an operating system. The software or firmware that creates a virtual machine on the host hardware is called a hypervisor or virtual machine monitor. [2]
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 application programming interface for applications programs (including some system software) and an interface to device drivers.
