New domain names are registered all the time, and ones previously registered expired. Sometimes that's the result of simple neglect. The owner of the name chose not to renew his or her ownership, so the name became available for someone else to use. In rare cases, a highly original mind managed to think of a new one. In the other common scenarios, someone chose to just let it go or sell it.

The way computers communicate is, in a way, very similar to something very familiar: the postal system that delivers letters and packages. Here's how...

The Internet is just what the name suggests, a large inter-connected set of networks. But those networks are pointless without the one part that forms what is called their 'end-nodes', otherwise known as computers. Those computers often need to share information because the people who use them want to share information.

Troubleshooting a network can take myriad forms. But most problems tend to repeat themselves over and over again. The first step is usually distinguishing between a software issue and a hardware issue. Unless you have specific reasons to question some other aspect of your system, start troubleshooting by checking the hardware on your network.

Admin is an overhead, there is no way round it, in this article we talk about DIY administration and what you need to consider.

For most web site owners, the primary focus is naturally on creating, maintaining and enhancing the site. That often is just part of managing an entire business, for which the web site is just the means to an end.

A network is like a simple spider web, the basic reason that the Internet is often called the world wide web. It's a series of lines (called routes) that have intermediate and end points (called nodes) that connect devices ie servers and hosts together. Those connections and routes are what allow the devices to share, input or output information across the network.

Along those routes, signals flow that contain information of interest to the network users in the forum of packets. Like a trapped fly that tugs on a part of the web, the disturbance is sent down the line, through nodes, to the spider or host at another point on the web. Unfortunately for the fly, the spider often sends back a reply.
