What is a Fully-Secured Computer?

The only fully-secured computer is one that is turned off. It is impossible to guarantee total security, especially once a computer is connected to a network, including the Internet.

PC’s Affect on Business Processes

A student recently commented, “Data can be manipulated, filtered and summed up directly by the person making the requests,” recognizes the effect of the personal computer on business processes.

Digitalis Americana – Wi-Fi Access on Vacation

Being away does not mean being gone.

When I originally wrote this article, I was visiting one of my favorite vacation spots in the United States: Hilton Head Island, South Carolina. I am shocked that a paucity of public life line networks the coffee shop down the road from our resort offers free wireless Internet service and the sundry store on the other side of the shopping doubles as an Internet café, selling access for $6.00 a day.

 

Digitalis Americana – Reliance on Digital Technology

Always on is not always good.

Reliance on digital technology creates a sense of emphasis on keeping busy and productive. The internet and the burgeoning world of e-business allow both geographic and chronologic flexibility.

When Software Bites, Back

McAfee’s antivirus software caused problems for Microsoft Excel users, on Friday. Just as Excel users, around the world, were attempting to complete their day’s work, the virus signatures, pushed to them by McAfee, caused the McAfee software to incorrectly identify the excel.exe file as being infected by the W95/CTX virus.

 

The Internet Freeway May Become A Toll Road

There are no traffic cops on the internet. Until now, that is. If U.S. telecommunication companies have their way, we may have internet traffic cops, patrol cars, and a full police union. The traffic cops will direct the traffic, giving preferential treatment to a select few that are able to pay for the unimpeded toll lane. Those who are able to pay the toll will get faster service.

 

Cellphone Users Beware: We Know Where You Are

Do you carry a cellphone? Do you know that your cellular service provider knows where your phone is? By extension, if you carry your phone with you, your cellular service provider knows where you are. Cellular phones can be located, accurate to within about 300 yards, whenever they are turned on. Since most cellular phone users keep their phones on and with them most of the time, it is quite probable that their ongoing whereabouts are being automatically tracked.

 

Almost Two-Thirds of U.S. Homes Have An Online Computer

According to the most recent U.S. Census data, 62 million households in the United States have an Internet-connected computer. That means just over half, 55 percent of homes have relatively easy access to the net, including e-mail and web resources. This data, current as of 2003, shows a five percent increase in connected computers, compared to the 2001 data, and more than triple the 18 percent connectivity rate reported in 1997.
