Cloud computing has become the latest trend in IT (Information Technology) industry. The term cloud computing refers to an infrastructure, designed with both hardware and system software, where data storage and computing uses data centres instead of personal computers, and the applications are distributed as services over the internet. It can be compared with a large pool which is easily accessible and contains vast amount of virtualized resources which can by vigorously reconfigured for optimum scale employment by adjusting variable load. Started only as a basic business concept, cloud computing has become the fastest growing trend in the IT industry in a few years. With more and more business organizations and individuals, cloud computing has grown large, and with that security has become a major issue in the field.

There has been a shift in the education sector away from the conventional and traditional classroom modes of learning to the use of ICT models and designs. Technology has revolutionized this sector enhancing the way students learn, share and understand courses. Many governments around the world, especially in industrialized countries like the UK and US, have launched several initiatives to promote this form of learning. In UK, the Education department has encouraged and aided projects like the national grid for learning and associated virtual teachers’ center. This essay will critically analyze the role of different ICT models in promoting learning, their impact as well as child development theories that support the use of these models

Cloud computing is a collection of an Information and supplies them in rental bases. In cloud computing Data-Security is a major and a serious issue as data is located in different forms in different places. Data-Security is most important technique for the future development in industries, business and some for the governments. This is relevant to both the hardware and a software this will deals to protect the data in the cloud environment. Cloud has many advantages like flexibility; efficiency, scalability, and integration they provide the operations in advanced and run their applications. One current research activity no going is the Fault-detection it is the building block of reliability and multi-cloud solutions and implement these characteristics on a cloud testbed. This paper will study about the security issue and challenge to overcome from data hacking. Security is the main challenge in the cloud computing it is the heart of the cloud to keep the data secure. This paper discuss about the various security issues and the possible opportunities are stated and resolve the issues based on the techniques in the cloud computing. The major security opportunity discussed in this paper is encapsulation of data among others

An m-commerce (mobile commerce) business model allows customers to complete every steps of the commercial transaction by utilising mobile phones rather than visiting to the physical or brick and mortar store. The experts of technology predict that the mobile wireless communications by 2020 are possibly to be available to anywhere and anyone throughout the globe at very low cost. But it is important to develop and maintain the trust and satisfaction of customers as well as reducing their risks involved in online payments and transactions.

Internet of things (IoT) refers to the relationship existing between the internet and a load of data transmitted. Users have widespread expectations about the repeated use of applications. Current explorations consider cloud computing as the foundation to make IoT the solution to several internet problems. Nevertheless, the IoT environment involves limitations with regards to the distance of several leaps from the information origin, geographically centralized architecture, and economic aspects. This paper present a Fog based IoT Health Care alternative structure and examines the diffusion of Cloud Fog services into interoperability Health Care solutions stretched upon the conventional Cloud-based structure. We used the iFogSim simulator that facilitates the simulation of the system and assists in the analysis of the results that are compared to a distributed computing network, data communication optimization, consumption of power by this system and latency reduction. The results aim at the improvement of cost at the instance, the usage of energy and the delays in the network

Cybersecurity refers to the state of protecting computers, networks, and data from unintended and unauthorized access, manipulation and destruction.
