Dynamic IP vs Static IP

  Static IP addressing is for one customer on one IP address and Dynamic IP addressing assigns a different IP address each time the ISP customer logs on to their computer, but this is dependent upon the Internet Service Provider (ISP) because some ISP's only change the IP address as they deem it necessary.
If you have Dynamic IP Addressing through your Website Host it means that you are sharing an IP Address with several other customers.
If you are a beginner on the internet, an avid internet user, are entertaining the thought of starting your own website business, are a gamer, use VOIP or VPN there are several things you should know about IP Addressing.
Static IP Addressing

If you feel the need to always know what your IP address is then you need a Static IP address, because it is constant. Static IP addresses are more reliable for Voice over Internet Protocol (VOIP), more reliable to host a gaming website or to play X-Box, Play Station, use Virtual Private Network for secure access to files from your company network computer, etc. Static IP addresses are also great if you use your computer as a server, as it should give your file server faster file uploads and downloads. Another plus with Static IP's, when hosting a website you are not sharing your IP with another company who sends out a lot of E-mail SPAM and not only has their website been shut down but in turn gets your IP address blacklisted.
In contrast a static IP address can become a security risk, because the address is always the same. Static IP's are easier to track for data mining companies. Static IP addressing is less cost effective than Dynamic IP Addressing.
Dynamic IP Addressing

The biggest advantages of Dynamic IP Addressing are less security risk as the computer is assigned a new IP address each time the customer logs on, they are cost effective and there is automatic network configuration (the less human intervention with network configuration the better). Dynamic addressing is usually used by ISP's so that one IP address can be assigned to several users, however some ISP's use Sticky Dynamic IP Addressing and do not change the IP address very often. Dynamic IP Addressing can be used by families with several computers or by a small business owner who has a home office. The software that comes with a router allows for Dynamic Host Configuration Protocol (DHCP) setup and assigns each computer attached to the router an IP address automatically.
In contrast, Dynamic IP addressing should not be used for VOIP, VPN, playing online games or game hosting because Dynamic IP addressing is less reliable then Static IP addressing and could cause the service to disconnect while you are on a VOIP, VPN or gaming.

A Brief Introduction to Web 3.0

Web 3.0If you ask some, they’ll tell you Web 2.0 as we know it is probably on its way out the door. For many, Web 2.0 is characterized mainly by the ability of users to share information quickly with others, which has been developed into the phenomenon that we call social media. From Twitter to Facebook to YouTube and to all sorts of other kinds of communities, Web 2.0 is all about sharing and seeing. Now if you recall or were around during what is now known as Web 1.0, information was put up on a website and that was it–the best way of sharing it was privately through e-mails and such. There was little to no communication and if you wanted information, you had to go to the source for it. Can you imagine such a harsh internet? Now with Web 2.0 on it’s way out, the obvious question is, what in the world is Web 3.0 going to be?

What is Web 3.0?

If you’re anything like me, it’s hard to imagine how the internet is going to top sites like Twitter and Facebook. But it’s bound to happen and when you research  Web 3.0, you find out it is going to be synonymous with the user’s interaction with the web. In Web 2.0 we focused on the users’ interaction with others, now we are going to focus more on the users themselves, which is always a plus. But how is this going to happen?
Web 3.0 is being referred to by experts as the semantic web; semantic meaning data driven. The data will come from the user and the web will essentially adjust to meet the needs of the user. For example, if you do a lot of searching for ‘design blogs’, you’ll receive more advertisements related to design. Also, when you search for other things, for example, ‘computers’, the web will keep in mind that you often search for design and may pull up search queries that combine ‘design’ and ‘computers’.

Benefits of Web 3.0?

A huge benefit of Web 3.0 is the move towards being able to access data from anywhere. This is mainly being driven by the heavy usage of smart phones and cloud applications. The idea here is to make sure that the user can access as much data as possible from anywhere, not  just their home. Technology is trying to expand this idea in ways that allow TV’s to pick up on user data, and allowing smart phones to access data on your computer. For designers like myself who typically forget their jump drives, this is an amazing and useful advancement!

Web 3.0′s Effect on Design

So now that you have an idea of what Web 3.0 is and what it’s going to be, we have to ask the most important question for us: what does that mean for design? Web 2.0 design was based around drawing attention and persuading your audience, because after all, web 2.0 made a huge deal about being able to purchase things online. Web 2.0 wanted to generate excitement and get people to make a purchase and understand what they were doing. You want to make a purchase? Sure, then click this button. You want to join the mailing list? Great, then there’s no question about clicking this button. That is the basis of Web 2.0 design.
Other elements were added to make things more fun and give a bit of style. The usage of linear gradients in web 2.0 is almost necessary. Whatever color combination you desire, linear gradients are typically present from your background to your buttons. Other trends surfaced like various badges, rounded corners and a necessary usage of icons. But again the question remains, what can we expect for web 3.0?

Web 2.0 Design vs. Web 3.0 Design

In web 2.0 we had to create design that was great for the web. I think in web 3.0, we will firstly have to create design that is going to be good not just for the web and the web browser, but for all sorts of media. With the growth in the usage of smart phones and tablets, people want more usage out of their items and to be able to access more things as best as possible. Design will have to be able to translate in great quality across all sorts of technologies. Now while you can create two different websites (one for the web and one for mobile devices), designers and developers will have to kill two birds with one stone, by creating one website that will look good in both environments.
Also for Web 3.0, designers will continue to focus on making things simpler. The truth is, the designer has the absolute power to persuade viewers on where to look first and second and so forth and so on. By doing this the designer creates a hierarchy of importance, that should not be muddled by useless design. Designers will continue to design so that content remains king by putting much focus on it and taking focus off non-content things such as logos and navigation bars.

Web 3.0 Design Trends?

Using these types of techniques plays into the increasing popularity of the minimalist design technique, where the focus is not necessarily making something as simple as possible, but making it as simplistic as possible. Creating a site with non-flashy web elements makes the user HAVE to focus on the content of the site. Of course designers desire to design and will ‘fancify’ some things, but in Web 3.0, that isn’t the main focus. The focus is to draw the viewers’ eye to the content or other important information on the page.
Many of the design trends used in Web 2.0 will only change by way of design, but not really the usage. The change in Web 2.0 to Web 3.0 is about how the internet is used, not really how it’s seen (with the exception of mobile devices and such). I believe designs will continue to get more and more minimalistic while maintaining a certain sense of beauty, but of course we will continue to use buttons and rounded corners and gradients. The design of Web 3.0 will be based on the way designers decide to design it and what becomes popular.

    I *think* I saw a Ted Talks relating to this – it wasn’t billed as ‘Web 3.0′, but it was discussing how data will be available in multiple formats, to multiple devices, providing a much more seamless experience for the user on the web.
    Simplicity is key for users – and the richness of Web 3.0 should enable them to interact with more information, more easily. If it works.
    Let’s not forget the design challenges still face in the web design community just dealing with old crap like IE6. Not to mention all the other combinations of browser and their inherent non-cross-compatibility ;-)
    Many Thanks,

Web 3.0 Technologies

Web 3.0

If you are excited about the Web 2.0 revolution in the past decade, I think you will be impressed by the next generation of Web applications.  Web 3.0 is already here and more Web 3.0 applications will emerge soon.  So, what is Web 3.0?  Web 3.0 is the next step in the evolution of the Internet and Web applications.  Here are several videos that you can learn about the concept of Web 3.0 and Web 3.0 development.  Hope you enjoy these videos and find them helpful to you.
Evolution Web 1.0, Web 2.0 to Web 3.0

The Future Internet: Service Web 3.0

               Web 3.0 : Semantic Web

Web 3.0 and its role in Education

This post is in response to Timbuckteeth's (Steve Wheeler's) post on Web 3.0 and e-learning 3.0:

As far as I have experienced it, Web 2.0 is Read/Write/Collaborate (varying shades of it).

From 'create a site', to 'collaborate using a site' to 'search/mash-up the data from n sources to get the best the web has to offer on what you want' is more like what Web 3.0 will have to offer.

Web 3.0 may or may not have more mobile technologies. Mobile technologies do not change the nature of activity that web is used for only it access. So mobile or static access will happen for Web 3.0 - I am not so sure at this stage. I do not care either.

From an institutional prospectiveThe educational use of Web 3.0 will enable read/write/collaborate and re-present the information to learners in a more meaningful way than what current technologies allow - Filtering/searching/mash up etc will play a big role in all this.

From a learner's point of view: Web 3.0 will further what web 2.0 allowed (i.e. read/write/collaborate) and help learners 'personalise' the information that is created via interactions in Web 2.0 to best suit their own needs.

So far, mainly constructivist principles have found resonance with what e-learning (Web 2.0) has to offer. Web 1.0 was more suitable for Behaviourist principles(online material/ quizzes/feedback etc). Web 3.0 will make the content King, again. Thereby making the cognitive approach to teaching and learning more prominent alongside behaviourists and constructivist approaches.

Learners will use the web to suit their style of learning using their PLE. Institutions will benefit from being able to blend different pedagogies using the web as they need to cater for many different types of learners. Some academics will make use of this more than other giving way to Personal Teaching Environments (PTEs) that make use of the web in this way.

Next big thing will be the content created collaboratively via the web primed for the best use of its users (more personalised). Somewhere the PTE will meet the PLE and Web 3.0 need to make the meeting of these two as smooth as possible.
I’ve listened to a few talks by Bruce Sterling concerning “the internet of things” and other Web 3.0 technologies. His idea of spimes (http://en.wikipedia.org/wiki/Spime) is very interesting.
Web 3.0
Web 3.0 is a term, which definition is not confirmed or defined so far as several experts have given several meaning, which do not match to each other, but sometimes it is referred to as a Semantic Web. In the context of Semantic Web, Web 3.0 is an evolving extension of the World Wide Web in which web content can be expressed not only in natural language, bu t also in a form that can be understood, interpreted and used by software agents, thus permitting them to find, share and integrate information more easily.
Tim Berners-Lee, the inventor of first World Wide Web has coined the term Semantic Web. But the concept of Web 3.0, first entered among the public in 2001, when a story appeared in scientific article written by American Coauthored Berners-Lee that described this term as a place where machines can read Web pages as much as humans read them e.g. web connected bathroom mirrors, which can read the news coming through on the web.
Definitions and Roadmap
There are several definitions of the web, but usually Web 3.0 is defined as a term, which has beencoined with different meanings to describe the evolution of web usage and interaction among the several separate paths.
These include transforming the Web into a database, a move towards making csontent accessible by
multiple non-browser applications, the leveraging of artificial intelligence technologies, the Semantic web, or the Geospatial Web. According to Wikipedia, an online encyclopedia, “Web 3.0 is a third generation of Internet based Web services, which emphasize m a c h i n e - f a c i l i t a t e d understanding of information in
order to provide a more productive and intuitive user experience.”. The third generation of Internet services is collectively consists of semantic web, microformats, natural language search, data-mining, machine learning,
recommendation agents that is known as Artificial Intelligence technologies or Intelligent Web.

According to some experts, “Web 3.0 is characterized and fueled by the successful arriage of artificial intelligence and the web”. While some experts have summarized the efinition defining as “Web 3.0 is the next step in the progression of the tubes that are the Internets”.
According to Nova Spivack, the CEO of Radar Networks, one of the leading voices of this newage Internet, “Web 3.0 is a set of standards that turns the Web into one big database.”
Steve, a famous Blog author has defined the term Web 3.0 as, “ Web 3.0 is highly specialized information structures, moderated by a group of personality, validated by the community, and put into context with the inclusion of meta-data through widgets”. While Leiki, the Finland based pioneer company of Semantic Web describes: “Web 3.0 makes the discovery of content streams effortless. It introduces automatic discovery of likeminded users and automatic tagging.”
The term ‘Web 3.0’ was first coined by John Markoff of the New York Times in 2006, while it first appeared prominently in early 2006 in a Blog article written by Jeffrey Zeldman in the “Critical of Web 2.0 and associated technologies such as Ajax”.
The debate originates in summit named Technet Summit in November 2006, in which various software tycoons expressed their views. e.g.
Jerry Yang, founder and Chief of Yahoo, stated:
“Web 2.0 is well documented and talked about. The power of the Net reached a critical mass, with capabilities that can be done on a network
