The principles architecture of standards, languages and formalisms that provides a platform for many heterogeneous applications same meaning and purpose of the web.

Many people create documents, but pre-Web the assumption was that a document was the private property of its creator, and decision to publish was his or hers alone.

Furthermore, the technology to allow people to publish and disseminate documents cheaply and easily was lacking, The Web’s aim was to alter that behavior radically and provide the technology to do it.

The Semantic web is an attempt to extend the potency of the web with an analogous extension of people’s beahaviour. And the semantic web is an extension of the WWW in terms of its being the next stage of linking –linkingdata not documents, so Linking is the key of the semantic Web.

The Web is engineering from php, HTML, XML and other language , its linking with the database to connect with the saving information that using SQL language and then web can be the social network, multi media, and more bussines with it.

The Web architecture build from simple technologies which connect with efficiently and usable and hope is it can grow further in the future.

The Web is a space in which resources are identified by Uniform Resource Identifiers (URI). There are protocols to support interaction between agents, and format to represent the information resources. These are the basic ingredients of the web.

Identification of resources is essential in order to be able to share information, reason, modify,or exchange. URI’s also connect the Web with the social world, in that they institutions.

The Web supports a wide variety of file formats, of which the most well-known is HTML and more formats possible use from the web, with it we can share more file and document with our friend and also we can sharing information to world.

From the aspect of web architecture, an important aim of web science is to identify the essential aspects of identification, interaction and representation that make the web work and to allow the implementation of systems that can support or promote desirable behavior.

And other aspect from methodology in web science, Web Science is a combination of synthesis, analysis and governance. In the rest of this text, we will take these three aspects in turn,, beginning with synthesis, then analysis, and then social issues that impact on web development, before finishing with a discussion of governace issues.
