One of our message board members recently wanted to set up their home network to access the programs and data on an old Windows 98 PC from a new Windows XP system. Accessing files is not too difficult, but being able to actually run Windows programs on one computer and see the interface on another requires more technical know-how.

The two approaches typically employed are called remote desktop and Virtual Network Computing (VNC). See the process one person went through to successfully get Windows Remote Desktop running on their home network. Discuss - Remote Desktop Connections

The U.S. ranks 15 in broadband network performance compared to other countries based on the latest Communications Workers of America (CWA) data. The average U.S. broadband connection runs at a modest 2.3 Mbps, CWA says.

Not coincidentally, the U.S. held the same position in last year's independent broadband study by the Organization for Economic Cooperation & Development. CWA also utilizes the speedmatters.org Internet Speed Test to compare U.S. states.

Scientists at UC Berkeley made news this week with a significant demonstration of light-bending metamaterials. For some reason, perhaps the excessive hours of Nethack we played in our younger years, this kind of research gets us excited about the idea of making (+0) cloaks of invisibility. This same technology, however, could be used for other, more realistic applications such as making high-speed networks route faster by slowing down optical signals.

UNC is a naming convention used primarily to specify and map network drives in Microsoft Windows. Support for UNC also appears in other operating systems via technologies like Samba. UNC names are most commonly used to reach file servers or printers on a LAN.

What is APIPA? Knowing the answer could help you land a job. Consider the example of Sam Marsh, a networking student in the UK who was recently asked this question during a technical interview. It's true APIPA is a relatively uncommon term, but the concept behind it is important.

As reported last month, prominent network researcher Dan Kaminsky uncovered a major DNS flaw that could have led to widespread Internet outages if not fixed. Technical details behind this flaw were shared publicly this week. Looking at the data, its clear that the potential for damage was huge. From injecting viruses into your emails, to snatching your credit card numbers using fake Web sites, hackers could have made our lives more difficult in several ways. Kudos to all involved in patching the DNS. → Read More - Internet Security Hole Revealed

Delta Air Lines announced today its plans to offer Internet access on all U.S. flights. Delta will apparently be the first U.S. carrier to offer wireless Internet on all of its routes. In-flight Wi-Fi technology finally looks to be ready for prime time after some aborted trials a few years ago. At roughly $10 USD per ticket, the service will certainly appeal to business travelers.

Cloud computing is an approach for using network technology to get work done and possibly save money. The term "cloud" refers generically to Internet hardware and software resources. Cloud computing makes these resources available to the public as network services.

Information Technology professionals build and deploy computer networks for organizations. IT is responsible for selecting, installing and maintaining network hardware and software systems. In some cases, IT also develops or enhances computer software to better serve the needs of the organization.

This week, one of our message board members reported a problem where their Windows Vista, XP and 2000 computers could not all recognize each other across the LAN. Our community quickly found the solution for this particular case. However, I hear reports of this type of problem frequently, and the fix isn't the same in every situation. Follow along on our message board if you'd like to contribute.
