Dave Murphy’s Student Resources Blog
Americans use multiple resources when searching for specific answers. The traditional sources, libraries and librarians, are still common alternatives, even with the ubiquitous availability of internet access.
Kojo Nnamdi, a radio host at WAMU interviewed Ryan Watkins and Michael Corry, authors of E-learning Compantion. More than three million students take online courses, annually. Watkins and Corry offer salient advice for both students and faculty who participate in a computer-mediated classroom.
Personal exposure and experience with using any technology is a definite asset; however, it is not by any means a prerequisite in the business environment. There are many technologies that we use on a daily basis without understanding how to create the technology. Good examples are our automobiles, televisions, and digital video recorders.
I agree with the process, write as we speak. I frequently recommend to writers that they aurally record their thoughts and then write their comments down, as they play back the recording. I have a microtape transcription machine (it was the only gift that I wanted for my 35th birthday), and I used it for many years, documenting my spoken lecture. Now, I use a digital voice recorder; however, the outcome is the same: I speak first, and then I write. I found that this process of speaking, then writing has helped my podcasting. I am now speaking, writing, speaking. 
In general, I judge that you, students, are able to demonstrate a clear command of the course content. Your class discussions are well focused, and your individual formal papers are prepared in a manner that coveys your comprehension the details of each week’s material.
However, in reading many assignments, I have noticed a pattern in your writing.
At the recent Chaos Communications Congress, Steven J. Murdoch, a researcher in the security group at the University of Cambridge, discussed how clock skew can be used to facilitate a digital attack against anonymity networks. Clock skew, the tendency for a computer’s clock to become less precise when heated, can reduce the efficacy of anonymizers, such as the Electronic Frontier Foundation’s Tor network.
Have you recently been receiving messages from a number of new friends? If so, you are either a good person or a one of the millions of spam victims. Experts estimate that 90% of e-mail traffic is spam, and those spammers claiming to be your friend may not really have your best interests at heart.
Creating a geographically-flexible workspace* has always been my dream. It took me ten years from the time that I first added this goal to my business plan to finally implement it. Since April 1, 2000, I have been working from a home office, a suite of 1,400 square feet that includes a private conference and reading room, office space, and a work room with a long bench upon which I can repair computers and assemble books. I even have my own kitchen and lavatory. If my refrigerator were a little larger, I could comfortably live here!

An ISP (Internet Service Provider) is the first link, for users, to the public Internet. AOL.com, PeoplePC.com, Comcast.net, Verizon.net are all examples of ISPs.
A podcast is a digital multimedia file that is distributed via the internet. Podcast listeners/viewers may download individual podcast files or subscribe to a subscription feed that automates the downloading of podcast episodes. Podcasts may be played on a personal computer; however, the inherent portability of the medium encourages use of a mobile playback device, such as a portable MP3 player.
Web sites must be hosted on a computer that is connected to the Internet. Domains, the alphanumeric names given to Web sites, must be registered and assigned to the site. Otherwise, it we be much more difficult to locate Web sites and practically impossible to address e-mail messages.

I use Macromedia HomeSite to create new and to edit complex pages. Even though the product has a WYSIWYG option, I prefer to edit in the standard text mode, using the preview mode to check the layout of my code. I specifically encourage novice designers to refrain from using Microsoft FrontPage and other solely WYSIWYG design applications, as each of them inserts extraneous code into the page that is not in keeping with the W3 HTML standard. The World Wide Web Consortium (W3) is the standards body for Web content development.

Plain Old Telephone Service (POTS), the old-style wireline telephone connection that was installed in our parents’ houses is quickly being replaced by Voice Over Internet Protocol (VOIP) service, which connects voice telephone calls through the always-on broadband connections that about half of Americans have in their homes.
You probably have seen the advertisements for VOIP (also called digital voice) on television; however, the company’s that advertise overcharge for their services. I suggest that you consider purchasing VOIP from other providers, one of whom sells the service at less than 10 percent of the cost of the television advertisers!
Sensitive digital data must be securely erased, once a computer system is marked for disposal!
I prefer to use Norton Ghost, which guarantees me the ability to reconstruct my primary partition (C: drive), in the event of a system failure or software corruption.
I am occassionally asked how to secure wireless networks and to confirm that machines are connected through the network. The two tools at our disposal are wireless encryption and the ping command. Wireless encryption comes in two versions, WEP and WPA.

As a rule of thumb, installing and uninstalling software applications does slow down a Microsoft Windows system, because the system registry becomes more complex. However, some utility products carry a low system footprint, and I judge, offer specific value that cannot be obtained through the applications included with Microsoft Windows, thereby outweighing a minor reduction in system performance.

Data files must be secured, especially if they were stored on a portable media device (USB thumb drive, CD, DVD) or a notebook computer. In addition to securing the data, the files must also be duplicated in a safe place.
A combination of two simple applications keeps my Microsoft Windows XP system registry in tune.
Flash memory devices have a write-erase life cycle of between 100,000 and 1,000,000 sets. I never thought of flash memory as being limited to the number of times a section of the media could be reused; I assumed that the media would be similar to hard disks, which fail mechanically before the media loses its ability to store and retrieve data.
