Sharing, management and on- demand allocation of network resources are particularly important in Cloud computing. Ho- wever, nearly all-current available cloud com- puting platforms are either proprietary or their software infrastructure is invisible to the rese- arch community except for a few open-source platforms.

This research is necessitated by the fact that apart from the point that globalization will be very difficult if not impossible without language, language is also a major tool to fix every challenge of life since solution to problems of life arises through thought. The researcher draws her data from bill boards, television, posters, and other secondary sources of data like textbooks, journals, internet, etc. and adopts a descriptive framework for the analysis of data. The investigation portrays the fact that language is an indispensable tool not only for global research but for resolving all the challenges facing Nigerians in the 21 st century. The study shows that there are challenges in the health, security, educational, social, economic, and political sectors in Nigeria. It equally reveals that through language, solution to the health, security, educational, social, economic, and political challenges in Nigeria is provided.展开更多
