Abstract: Several computing technologies have emerged by the end of 20 th century due to the high speed Broadband internet with each having a number of applications in science, engineering, business, social systems, and governments. These technologies brought revolutionary changes in communications and computational processes. In- fact the advances in hardware, investigation of sophisticated rigorous mathematical algorithms are also responsible for greater shift in these developments. Some of these computing technologies are cluster, grid, and cloud, cloud-mobile. Multi-cloud, parallel, concurrent, distributed, DNA, mobile, high performance, utility, global cooperative, functional, ubiquitous, pervasive, exploratory, quantum, scalable computing, ubiquitous secure, computational grid, etc. In this paper we review uses and practical applications. Research into enhancing the technology, utility in various application areas have been growing at fast phase. It may stimulate further study of each and the convergence of all these technologies in dealing with logistic based problems of large dimensionality.
