Disaster Plan

...| Disaster plan | | | | 6/6/2010 | | Abstract This is a disaster plan that I created for the IST Department of XYZ Computers company in order to prevent any future problems that may arise such as the situation they had over the weekend when a major water pipe broke and flooded the first floor, causing extensive damage to the servers. Included in the disaster plan I will address a few issues that will aid the company in protecting against such things as any natural disasters that may occur as well as any other occurrences that may deem necessary for such a disaster plan. I will detail my recommendations for using a RAID system for data protection in order to have a well placed back up plan with the most up to date information possible. In short I plan to properly detail a disaster plan the best possible way that I can in order to have a good disaster recovery plan in place rather than having to spend the time and money on extra recovery efforts. Hopefully having such a plan in place will keep from losing important data to unforeseen issues, such as natural disasters due to the geographical location among other issues that may arise at the most in opportune time possible. When creating a disaster plan the first thing to keep in mind is to do a complete risk assessment of the entire existing computer systems. In order to accomplish this task all the risks and probabilities will need to be noted such as any delays to system uptime and how close at hand these...

... 2012). Bleeding technology is relatively, new technology. Bleeding technology is unreliable because it has not been tested and it has not proven its worthiness or authenticity. A user will be taking a huge risk to use the bleeding technology which would be more expensive than the leading technology. Bleeding edge technology could be very costly and it could turn into something that could be the beginning of a serious problem. The reason why bleeding edge technology could cause many problems is because it is new and might be quite risky because of the instability.

Computer as a Catalyst for Change

...1 Teachers’ Views of Computers as Catalysts for Changes in Their Teaching Practice Sara L. Dexter and Ronald E. Anderson University of Minnesota Henry Jay Becker University of California, Irvine This paper was published in the Journal of Research on Computing in Education. The citation for it is: Dexter, S., Anderson, R. E., & Becker, H. J. (1999). Teachers’ views of computers as catalysts for changes in their teaching practice. Journal of Research on Computing in Education, 31 (3), 221239. Abstract: In this study we examined the use of computers by teachers in their instructional practices and their perception of the impact of computers on changes they have made to their classroom practice. These data draw from 47 teachers from 20 K-12 schools across 3 states who each completed a questionnaire, participated in 3 semi-structured interviews, and allowed 3 observations of their classroom. The teachers who had adopted more progressive teaching practices over time felt computers helped them change but they did not acknowledge computers as the catalyst for change. Instead, they cited catalysts that included: reflection upon experience, classes taken, and the context or culture of the school. We conclude that in order for teachers to implement the use of educational technology in a constructivist manner, they must have opportunities to construct pedagogical knowledge in a supportive climate. Research funded by the program of Research on Education Policy and Practice at the National...

Operating Systems on the Internet

...Internet Operating Systems For years I thought that operating systems were simple little programs (lines of code) placed inside personal computers to help them run smoothly and efficiently (truth be known, an OS is needed to make any computer run at all). But not until recently did I discover that operating systems must also be used in larger mainframes and servers as well. After all, servers are computers too! And any computer, regardless of its size or purpose, needs internal instructions. It needs a set of executable code that makes the thing come alive. One might say that operating systems are the souls of computers everywhere. This begs a question or two: what types of OS’s are out there? And how do they differ from the one in my iPhone? Also, if I wanted to swap out my current operating system for a different one (after all, my friends keep telling me about all of the great things they’re doing with Linux), how easy of a task would that be? The most common OS for a desktop (or a laptop) in use today is Windows 7 ("Os Platform Statistics", 2012). But what about the operating systems which are used by small and large companies that host web pages? Or what about the large computers that store hundreds of thousands (if not millions) of large data files in a centralized data centers? Or what about those companies that provide search engine services? Companies like Google, facebook, and Yahoo!, maintain their own, internal OS’s, which are designed to serve...
