Discussions with a central IT organization about integration with existing systems on campus, support costs for the new implementation, and total cost of ownership frequently become adversarial. Simmons College, a small college in Boston with an enrollment of approximately 1,900 undergraduate and 2,800 graduate students, reframed these issues in…

After starting off as a simple way to provide users with access to internet resources, WiFi networks have evolved to become an important communications cornerstone for a growing number of academic institutions. Not only have colleges been working to make these networks available across their entire campuses (or at least pretty close to 100 percent…

Discusses Internet protocol (IP) and subnets and describes how IP may operate over asynchronous transfer mode (ATM). Topics include TCP (transmission control protocol), ATM cells and adaptation layers, a basic architectural model for IP over ATM, address resolution, mapping IP to a subnet technology, and connection management strategy.

Wireless technologies have revolutionized the ways teaching and learning have become in many colleges and universities. It is therefore interesting to observe the way wireless technologies are used to organize small group meetings. It provides online access to internet resources such as instructor lecture series. It finally helps in…

Our paper reports findings from a two-phase deployment of iPod Touch and iPad devices in a large, urban Canadian school board. The purpose of the study was to gain an understanding of the infrastructure required to support handheld devices in classrooms; the opportunities and challenges teachers face as they begin to use handheld devices for…

In this paper, we present the characteristic features of distributed applications. We also enumerate the modalities of optimizing them and the factors that influence the quality of distributed applications, as well as the way they are affected by the optimization processes. Moreover, we enumerate the quality characteristics of distributed…

Using animated visualization tools has been an important teaching approach in computer science education. We have developed three visualization and animation tools that demonstrate various information security concepts and actively engage learners. The information security concepts illustrated include: packet sniffer and related computer network…

In early 2009, Congress directed the Federal Communications Commission (FCC) to develop a National Broadband Plan to ensure every American has "access to broadband capability." Congress also required that this plan include a detailed strategy for achieving affordability and maximizing use of broadband to advance "consumer welfare, civic…

This is a special issue published in version 1.0 of "Global Journal of Computer Science and Technology." Articles in this issue include: (1) [Theta] Scheme (Orthogonal Milstein Scheme), a Better Numerical Approximation for Multi-dimensional SDEs (Klaus Schmitz Abe); (2) Input Data Processing Techniques in Intrusion Detection…

When using mobile devices in support of learning activities, students gain mobility, but problems arise when group members share information. The small size of the mobile device screen becomes problematic when it is being used by two or more students to share and exchange information. This problem affects interactions among group members. To…

Wireless connectivity in schools is all the rage, and many school systems have at least gotten their feet wet with a wireless lab or a few portable laptop carts. But Bijaya Devkota, the chief information officer of Charles County Public Schools, has done what many school systems only dream of--implemented universal wireless access throughout his…

This study explores whether university students find that laptop computers and networks increase flexibility and effectiveness of studying. Special attention has been paid to non-traditional students who have extra commitments, such as taking care of children or term-time employment. Questionnaire data was collected from students who had the…

This article describes how centralized presentation control systems enable IT support staff to monitor equipment and assist end users more efficiently. At Temple University, 70 percent of the classrooms are equipped with an AMX touch panel, linked via a Netlink controller to an in-classroom computer, projector, DVD/VCR player, and speakers. The…
