This study assessed Information and Communication Technology (ICT) Proficiency of Secondary School Teachers in Auchi Polytechnic Staff School. The study employed a descriptive surveyed design and purposive sampling techniques to select fifty-three (53) respondents for the study. A structured questionnaire was used to collect data. The data…

Cloud computing platforms can be highly attractive to conduct course assignments and empower students with valuable and indispensable hands-on experience. In particular, the cloud can offer teaching staff and students (whether local or remote) on-demand, elastic, dedicated, isolated, (virtually) unlimited, and easily configurable virtual machines.…

Digital technology has irrevocably altered the nature of the archive. Drawing on materialist critiques and the evolving field of media archaeology, this essay explores new strategies for understanding the implications of computer networks in libraries. Although a significant portion of the contemporary literature within Library and Information…

In this dissertation, we discuss the problem of enabling cooperative query execution in a multi-cloud environment where the data is owned and managed by multiple enterprises. Each enterprise maintains its own relational database using a private cloud. In order to implement desired business services, parties need to share selected portion of their…

Despite the recent advances in systems and network security, attacks on large enterprise networks consistently impose serious challenges to maintaining data privacy and software service integrity. We identify two main problems that contribute to increasing the security risk in a networked environment: (i) vulnerable servers, workstations, and…

Large-scale enterprise applications are deployed as distributed applications. These applications consist of many inter-connected components with heterogeneous roles and complex dependencies. Each component typically consumes 5-15% of the server capacity. Deploying each component as a separate virtual machine (VM) allows us to consolidate the…

Virtualization enables the ability to consolidate multiple servers on a single physical machine, increasing the infrastructure utilization. Maximizing the ratio of server virtual machines (VMs) to physical machines, namely the consolidation ratio, becomes an important goal toward infrastructure cost saving in a cloud. However, the consolidation…

The facts that the wireless technologies (1) are more convenient; and (2) need less skill than desktop computers, play a crucial role to decrease digital gap in rural areas. This study employed the Bayesian Confirmatory Factor Analysis (CFA) to design a mobile training system in rural areas of Iran. It categorized challenges, potential, and…

Just as maintaining a healthy infrastructure of water delivery and roads is essential to the functioning of cities and towns, maintaining a healthy infrastructure of information technology is essential to the functioning of universities. Deterioration in IT infrastructure can lead to deterioration in research, teaching, and administration. Given…

Use of the Patch Vulnerability Management (PVM) process should be seriously considered for any networked computing system. The PVM process prevents the operating system (OS) and software applications from being attacked due to security vulnerabilities, which lead to system failures and critical data leakage. The purpose of this research is to…

Virtualization technology has been around for many years, and its use is increasingly becoming common in education, in general and in computing fields, in particular. This can be attributed partly to its potential to reduce costs, boost efficiency and overcome limited resources through its virtual applications such as servers, storage devices and…

This thesis uses the tool of network coding to investigate fast peer-to-peer file distribution, anonymous communication, robust network construction under uncertainty, and prioritized transmission. In a peer-to-peer file distribution system, we use a linear optimization approach to show that the network coding framework significantly simplifies…

Information Technology (IT) business value research is suggested as fundamental to the contribution of the IS discipline. The IS research community has accumulated a critical mass of IT business value studies, but only limited or mixed results have been found on the direct relationship between IT and firm performance. Extant studies mostly focus…

Purpose: Mobile data traffic globally is increasing rapidly in both enterprise and consumer segments. The purpose of this paper is to identify a new network architecture and opportunity that support ubiquitous mobile work for higher-education institutions. Design/methodology/approach: It reviews existing literature and enabling technologies and…

The back-end databases of multi-tiered applications are a major data security concern for enterprises. The abundance of these systems and the emergence of new and different threats require multiple and overlapping security mechanisms. Therefore, providing multiple and diverse database intrusion detection and prevention systems (IDPS) is a critical…
