What is IPV6 ?

IP, the Internet Protocol, is one of the pillars which supports the Internet. Almost 20 years old, first specified in a remarkably concise 45 pages in RFC 791, IP is the network-layer protocol for the Internet. In 1991, the IETF decided that the current version of IP, called IPv4, had outlived its design. The new version of IP, called either IPng (Next Generation) or IPv6 (version 6), was the result of a long and tumultuous process which came to a head in 1994, when the IETF gave a clear direction for IPv6. IPv6 is designed to solve the problems of IPv4. It does so by creating a new version of the protocol which serves the function of IPv4, but without the same limitations of IPv4. IPv6 is not totally different from IPv4: what you have learned in IPv4 will be valuable when you deploy IPv6. The differences between IPv6 and IPv4 are in five major areas: addressing and routing, security, network address translation, administrative workload, and support for mobile devices. I...

How The Internet Affects Your Brain

Like most things, the Internet has its good and its dark side. And, considering the pervasiveness of the Internet in society, it is certainly having an effect on our brains. After all, everything we do affects our brain. Though up until the 1980’s, it was universally believed that the steam engine was the foremost invention of the Industrial Revolution, technology and science historian, Lewis Mumford, had long before proposed that that clock was in fact the key machine of the modern Industrial age. And, just as people began operating and planning according to seconds and minutes, in the age of the internet, we are rewiring our “plastic” brain to function more and more like computers. Processing, decoding and storing floods of information at a rate faster than we ever have before, our brains are becoming highly adapted to taking on scores of tasks at once.

So, What is a Content Management System Anyway?

Overview ============ In practice, you will find that most CMSs are not usually devoted to managing only application content or even a combination of information and application content. In most cases, CMS software developers focus on information management only and let other software developers build tools, such as source code management systems, to handle the application content. With that said, many high-end, high-priced, commercial CMSs support the allencompassing definition of content. Vignette and Interwoven are two such CMS systems. They both support practically any type of information content that can go on a Web site, as well as deployment of any custom applications. An interesting note about these CMSs is that they offer the application content management system as an add-on package. So, it appears that even they see the distinction between the two types of content. Yet still, in light of all this, there is evidence that the industry is in the process of trying ...
