Scientists have found a new way to tell age though eyes. The new technique uses radiocarbon dating to measure special proteins known as lens crystalline that develop during birth and remain unchanged for the rest of our lives. With the help of this technique the researchers have correctly identified the ages of 13 people within one and half years by analyzing a carbon isotope called carbon-14 trapped inside the crystallines. The technique employed in the lens analysis is based on the sudden increase in atmospheric carbon 14 beginning in the 1950s until a test ban a few years later. Scientists have recorded these levels annually, giving them a benchmark to date a person’s birth by matching corresponding year in which the carbon 14 atmospheric content was as high as in person’s eye lens.

The present generation is the generation of computers. We cannot think of modern world without computers. As the technology is improving day by day computers are becoming more and more sophisticated. The present generation of computers is of laptops. A laptop computer, or simply laptop (also notebook computer or notepad), is a small mobile computer. Laptops are capable of the same tasks as a desktop computer, although they are typically less powerful for the same price.

They contain components that are similar to their desktop counterparts and perform the same functions, but are miniaturized and optimized for mobile use and efficient power consumption. These laptops are small and easy to carry. Laptops generally make use of Liquid Crystal Displays. In addition to built in keyboard they may utilize touchpad or pointing stick for input. The modern laptops come with all new features like high capacity RAM’s, graphics card, DVD writer and card readers, etc. So, next time, when you think of buying computers, definitely go for laptops.

With the development of new technologies and the internet, accessing of information and data has become much easier. But along with the convenience and speed of access to information come new risks of data security. If information and data are recorded electronically and are available on networked computers, they are more vulnerable and prone to theft and loss than if they were same information printed on paper and locked in a file cabinet. The simple reasoning is that, digital data are more prone to data thefts and so they must be kept more securely. Here comes the importance of utilities like SecureZip which keeps the data in a more secure way.

SecureZIP - the next generation of ZIP, is new software which comes with complete feature of securing your data. You can go directly to www.securezip.com and download it for free. The free download is a limited time offer and so you should act fast if you want to grab a copy of this great software without having to spend a single penny. The best thing about the free download offer is that, it comes with full individual user license and it is not trial software. That means you get all the features and still you get it for free.

The installation process is also damn easy and you will the simplicity of the user interface. Just launch the executable file and you will be guided what next to click. And with just a few clicks, the software is ready to be put to use. So, grab your free copy of the great secureZIP software before they close the offer and get your data secured. Remember, better security means better efficiency and better productivity with less trouble and less anxiety.

Worldwide Interoperability for Microwave Access, popularly known as the WiMAX refers to broadband wireless networks that are based on the IEEE 802.16 standard, officially known as the WirelessMAN. The WiMAX standard specially ensures the compatibility and interoperability between various broadband wireless access equipments, which uses the IEEE 802.16 protocols for standard communication. The WiMAX has a range of up to 31 miles, and is primarily aimed at making broadband network access widely available without the expense of stringing wires. We may recall here that WiMAX has much wider area coverage than the standard Wi-Fi network. A typical Wi-Fi home router using 802.11b or 802.11g with a stock antenna might have a range of only 45 m indoors and 90 m outdoors.

In the words of the WiMAX Forum (the organization dedicated to certifying the interoperability of various WiMAX products), WiMAX is “a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL“. This standard will provide high-speed data and telecommunications services and a diverse source of Internet connectivity. Another great advantage of WiMAX is its backward compatibility with the Wi-Fi Standard networks. That means with WiMAX, you can connect Wi-Fi hotspots with each other and to other parts of the Internet. However, we should remember that WiMAX is very different from Wi-Fi in the way it works.

Sometimes, the WiMAX network may be confused with the Wi-Fi network. It is true that both standard uses the IEEE 802.xx protocols, but the two are very different in the way they work as well in the features they provide. The main difference being the network range each standard can cover. The WiMAX uses licensed spectrum to deliver a point-to-point connection to the Internet from an ISP to an end user while the Wi-Fi uses unlicensed spectrum to provide access to a network, typically covering only the network operator’s own property.

The advantages of the WiMAX technology was clearly seen when it was used for communication in Aceh, Indonesia, after the attack of the Tsunami in December 2004 when all other communication infrastructures in that area were destroyed making the surviving people unable to communicate with people outside the disaster area and vice versa. Seeing its potential, many companies today are closely monitoring the development of this technology. Big cellular companies, like the Sprint Nextel has already announced its USD 300 Billion investment policy in a big WiMAX Technology buildout over the next few years. The trend is still going. In fact, this trend of high-end technology development in the field of communication will never stop growing. The electronics and telecommunication industry spearheaded by Samsung Electronics and ETRI in Korea has even developed its own standard called the WiBRO and Intel and LG Electronics has already agreed on interoperability between WiBro and WiMAX.

Biometric authentication is the new technology that measures and analyzes human physical and behavioral characteristics for authentication purposes. It may involve fingerprints, eye retinas and irises, facial patterns and hand measurements, while examples of mostly behavioral characteristics include signature, gait and typing patterns. One can find the best Biometric solutions at penflow.com

Digital signature, on the other hand, is something similar to an electronic signature which may be defined as an electronic sound, symbol, or process, attached to or logically associated with a record and executed or adopted by a person with the intent to sign the record. Digital signature and electronic signature are also increasingly becoming not only popular, but also a necessarily in today’s world. They are on their way?to build what is so called the Paperless Office era. One can look for the best digital signature services and solutions yet again at penflow.com

Irgent is new generation messaging tool that facilitates us to read and send emails, fax and text messages in a new and wonderfully fast and secure environment. Not only text, but we can also use the Irgent tools for our voice communications. Irgent system is on their move to completely revolutionize text messaging services with what they call the “profile based multi-modal” messaging. Instead of addressing your messages to a specific address (e.g., email address, telephone or fax number), using Irgent you just address a message to a recipient’s name. They are fast and efficient and at the same time secure. You can broadcast fax, send voice mails and what more.

The billing systems of this wonderful communication system enhancement is also very flexible to suit all our needs.
