In the age of COVID-19, traditional teaching techniques are under scrutiny. Most concepts and labs in the area of information technology are intended to be taught face-to-face in labs using clusters and networking infrastructure. Simulation software's such as uCertify, Pearson online, etc.., are good alternative, but are not always a viable…

Cloud computing is a rapidly emerging topic, but should it be included in an introductory IT course? The magnitude of cloud computing use, especially cloud infrastructure, along with students' limited knowledge of the topic support adding cloud content to the IT curriculum. There are several arguments that support including cloud computing in an…

The use of cloud computing services has grown dramatically in post-secondary institutions in the last decade.

All Computer Information Systems programs require a database course for their majors. This paper describes an approach to such a course in which real world examples, both design projects and actual database application projects are incorporated throughout the semester. Students are expected to apply the traditional database concepts to actual…

We want our students to experience system testing of both desktop and web applications, but the cost of professional system-testing tools is far too high. We evaluate several free tools and find that AutoIt makes an ideal educational system-testing tool. We show several examples of desktop and web testing with AutoIt, starting with simple…

In demand paging virtual memory systems, the page fault rate of a process varies with the number of memory frames allocated to the process. When an increase in the number of allocated frames leads to an increase in the number of page faults, Belady's anomaly is said to occur. In this paper, we present a probability model for Belady's anomaly. We…

Passwords have the distinction of being the most widely-used form of authentication--and the most vulnerable. With the dramatic increase today in the number of accounts that require passwords, overwhelmed users usually resort to creating weak passwords or reusing the same password for multiple accounts, thus making passwords the weakest link in…
