The above article defines Web 1.0 and Web 2.o as follows:
"Think of Web 1.0 as a library. You can use it as a source of information, but you can't contribute to or change the information in any way. Web 2.0 is more like a big group of friends and acquaintances. You can still use it to receive information, but you also contribute to the conversation and make it a richer experience."
Now what is Web 3.0??????
What will Web 3.0 look like????
In a nutshell, here is what Web 3.0 will look like and feel like....
"Internet experts think Web 3.0 is going to be like having a personal assistant who knows practically everything about you and can access all the information on the Internet to answer any question. Many compare Web 3.0 to a giant database. While Web 2.0 uses the Internet to make connections between people, Web 3.0 will use the Internet to make connections with information. Some experts see Web 3.0 replacing the current Web while others believe it will exist as a separate network.?
How will it work????????????????
"Some experts believe that the foundation for Web 3.0 will be application programming interfaces (APIs). An API is an interface designed to allow developers to create applications that take advantage of a certain set of resources. Many Web 2.0 sites include APIs that give programmers access to the sites' unique data and capabilities. For example, Facebook's API allows developers to create programs that use Facebook as a staging ground for games, quizzes, product reviews and more."
Others think Web 3.0 will be a Semantic Web...
"With the Semantic Web, computers will scan and interpret information on Web pages using software agents. These software agents will be programs that crawl through the Web, searching for relevant information. They'll be able to do that because the Semantic Web will have collections of information called ontologies. In terms of the Internet, an ontology is a file that defines the relationships among a group of terms."
To sum it all up...
"Even though Web 3.0 is more theory than reality, that hasn't stopped people from guessing what will come next. Keep reading to learn about the far-flung future of the Web."
The information in this article is so informative that I had to just quote what the article had to say. Web 3.0 is up and coming. I can see it coming soon. Once the technology is developed it will be here.
