When attempting to get a software product to reach a larger part of the market, portability is a key factor. However, in many cases, the software is installed on a computer in a way which depends upon its detailed hardware, software, and setup, with device drivers for particular devices, using installed operating system and supporting software components, and using different drives or directories. Cultural and Social Constraints on Portability. The prerequirement for portability is the generalized abstraction between the application logic and system interfaces. The article concludes with four suggestions for further research within the context of software engineering and educational software portability. Drive letters and the backslash as path delimiter are not accepted on all operating systems. Lines of Code (LOC), or LOC in thousands (KLOC), is an i… It is the only book published on the subject. Non-web programs, installed upon a computer in the normal manner, can have more control, and yet achieve system portability by linking to portable libraries providing the same interface on different systems. A Course in Software Portability James D. Mooney Dept. Software which is not portable in this sense will have to be transferred with modifications to support the environment on the destination machine. Porting 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. I've learned that compilers are ISA specific. This is usually measured in terms of the maximum amount of effort permitted. Software engineering factors related to portability—such as factors related to the student-computer interface, authoring, and choice of design model—are also discussed. While any system with a high degree of complexity, containing software, will be hard to reach a certain level of reliability, … Lack of conformance to requirement is lack of quality. 3 Overview 5 Supportability Principles Lesson’s Learned Key Phase Recap Conclusion Contact Information. Software can be compiled and linked from source code for different operating systems and processors if written in a programming language supporting compilation for the platforms.
