Sometimes, the most relevant layer for a specific software is called a computing platform in itself to facilitate the communication, referring to the whole using only one of its attributes – i.e. using a metonymy. For example, in a single computer system, this would be the computer's architecture, operating system (OS), and runtime libraries. [2]
The rise of the Internet and cloud computing enabled a new model, software as a service (SaaS), [18] in which the provider hosts the software (usually built on top of rented infrastructure or platforms) [19] and provides the use of the software to customers, often in exchange for a subscription fee. [17]
Another approach is to use software that hides the differences between the platforms. This abstraction layer insulates the application from the platform. Such applications are platform agnostic. Applications that run on the JVM are built this way. Some applications mix various methods of cross-platform programming to create the final application.
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).
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.
System software is a generic term referring to the computer programs used to start and run computer systems including diverse application software and networks. Computer programming tools, such as compilers and linkers, are used to translate and combine computer program source code and libraries into executables, which are programs that fall ...
Application software is any computer program that is intended for end-user use – not operating, administering or programming the computer. An application ( app , application program , software application ) is any program that can be categorized as application software.
In computer programming, a software framework is an abstraction in which software, providing generic functionality, can be selectively changed by additional user-written code, thus providing application-specific
