World Wide Web

      

       The Web or World Wide Web (WWW) is a way of accessing information via internet. It contains information (documents and other web resources) are identified by Uniform Resource Locator (URLs)

      The Web was invented by Tim Berners, an English scientist in 1989. In 1990, while employed at CERN in Switzerland, he wrote the first web address.

      WWW is important because it connects the world and made it easier to communicate with others. It allowed us to share our thoughts and let the whole world hear our voices. WWW also made it much easier for people to share and gain information.

The Web 1.0

Web 1.0 was the first stage of the World Wide Web’s evolution. Basically, content creators provided content for the vast majority of users who were only consumers or readers of that content.

The most important features of Web 1.0 were as follows:

• It was a read only web
• It was based on HTML which is a basic computer language.
• It was characterized by static pages (there is no interactivity between users and websites).
• It was also characterized by slow connection speed.
• The software was very expensive, generally on CDs or DVDs to be installed.

Web 2.0

Web 2.0 was the next evolution of the Web. It is more sophisticated and is characterized by its social aspect. Unlike Web 1.0, Web 2.0 is a many-to-many relationship.

Here are the features of Web 2.0:

• It is a read-and-write web.
• It is based on more sophisticated computer languages (PHP, Mysql, Java Script…)
• The pages are dynamic pages, which means that there is the possibility of interactivity between users and the web.
• It is characterized by speed.
• The software is more accessible. It is on line or downloadable.

Web 3.0

Web 3.0 is an evolution of the Web as an extension of Web 2.0. It is also called the Semantic Web. It is characterized by connective intelligence, connecting data, concepts, applications and ultimately people.

Here are its features:

• Read, write and execute web.
• Users are served more intelligently.
• Personalized information.
• Machine comprehension.
• Cloud Technology.
• Everything is connected.
• Immersion.
