Software reusability in green computing / Ibraheem Y. Y. Ahmaro

Green technology involves a wide range of subjects, from new energy-saving techniques
to advanced materials innovation that can be applied to daily life. Its main goal is to
protect the environment from harmful effects that technology sometimes brings. Green
computing has taken off in Malaysia but not all information technology companies in the
country see its long-term benefits. Although most green computing initiatives have
concentrated on innovating hardware, little attention has been paid to the software aspect
and how it can enhance green computing. This research shows how software reusability
can promote green computing and to illustrate this point, quantitative analysis method is
used to gather data from questionnaires distributed among the employees of IT companies
in Malaysia. The questionnaire has been structured into three sections to meet the main
goal, to achieve the objectives of this study and answer the research questions. The data
collected will be thoroughly examined before it is tabulated or published. Reliability
analysis, factor analysis, normality analysis, correlation analysis and regression analysis
are used to analyze the amassed data. It can be discerned that the main software
reusability approaches used in the IT industry include design patterns, component-based
development and application frameworks. Telecommuting is the main green computing
approach while algorithmic efficiency, power management, voice over internet protocol
(VOIP) and virtualization approaches are also commonly used methods. The implication
of this study to IT companies in Malaysia is that it substantiates the benefits of software
reusability practices which drive savings in development costs. It also highlights software
reusability as an important method in preventing the negative effects of global warming
and maintaining environmental sustainability.
