Inkjet Vs Laser Printer
In the early days there was a vast difference between an inkjet printer and its laser version but with time the difference has narrowed down to point where it is sometimes difficult to differentiate between the two. Most individuals continue to use the inkjet printers, as they are less expensive and nearly all of them are colour capable. The quality of the inkjet printers has improved over time and now there is not a huge difference in printing quality with the Laser printers. It's for this reason that small or home business can use an inkjet printer without having to worry about documents looking unclear or looking cheap. The laser printer is capable of printing much faster and usually produces...
Steal This Email!
Ample media attention has been focused on security issues such as viruses, phishing attacks and theft of sensitive customer information from large databases. The proliferation of Spyware and Malware (malicious software) has also garnered media attention. Another major, yet seldom discussed threat which goes on largely ignored outside the IT community is the theft and redistribution of email.To make a product which best addresses the quiet rise in email thuggery, sometimes we have to think like a criminal or mal-doer. How would these digital thugs hunt for Personal Identifying Information (PII), company assets or secret email conversations intended to be read ONLY by the recipient? Consider this...

It's not surprising that this lack of understanding is what leads to shockingly high phone bill surprises. So if you want to prevent getting one it's important to have a basic understanding of how they work. You basic cell phone plans come with a monthly allotment of anytime minutes, and usually free or night and/or weekend minutes. When you make a call the thing to understand is the phone company is going to use the most expensive minutes first. For example let's say your plan has 200 minutes per month. During the first week of the month all of your calls are...

The Metaphors of the Net
I. The Genetic BlueprintA decade after the invention of the World Wide Web, Tim Berners-Lee is promoting the "Semantic Web". The Internet hitherto is a repository of digital content. It has a rudimentary inventory system and very crude data location services. As a sad result, most of the content is invisible and inaccessible. Moreover, the Internet manipulates strings of symbols, not logical or semantic propositions. In other words, the Net compares values but does not know the meaning of the values it thus manipulates. It is unable to interpret strings, to infer new facts, to deduce, induce, derive, or otherwise comprehend what it is doing. In short, it does not understand language. Run an...

What You Should Check Before Buying Wireless Equipment
When you buy wireless equipment, you want to make sure that everything you buy will work in your house with the computer(s) you already have and over the distances required. Before you spend any money on equipment, consider the following issues. Find out about the construction of your walls. In theory, wireless technology is capable of passing through walls and other obstacles relatively easily. However, in reality, some walls are of a thicker or more solid construction than others and may block some of your wireless signals. You only need to consider the interior walls, of course, and you will need to consider floor construction if you want to use your wireless network on different levels...
