Do not confuse over Internet and Web considering it as a same thing. Both are different, web uses internet to send the data.
Timothy Berners Lee created WWW in 1989 at CERN in Geneva. WWW is proposed by him allowing researchers to work together effectively and efficiently at CERN making it World Wide Web.
Below diagram explains the evolution of World Wide Web:
Architecture is classified into many layers as shown below.
Uniform Resource Identifier (URI) is used to identify the web resources and UNICODE makes it possible to built web pages that are readable and writeable in human languages.
XML (Extensible Markup Language) helps in defining common syntax in semantic web.
Resource Description Framework (RDF) framework helps to define core representation of information for web. RDF represents the data about resource in graphical form.
RDF Schema (RDFS) offers standardized description of taxonomies and different ontological constructs.
Web Ontology Language (OWL) provides more constructs than RDFS. Below are its three versions:
RIF and SWRL supplies rules way beyond the constructs that are provided from RDFs and OWL. Simple Protocol and RDF Query Language (SPARQL) is SQL like language used to query RDF data and OWL Ontologies.
All the rules and semantics that are executed in layers below Proof with their result will be used to prove deductions.
Verification of the origin of sources in means of digital signature is called Cryptography.
The top layer User interface and Applications layer is built for serving user interaction.
Now the browser gets the web page. After interpreting it, contents are displayed in browser’s window.
Future of the web is unpredictable as there is a vast development in this field impacting every area such as education, research, commerce etc.
Even though there is a huge development in the field of WWW, there are some technical issues that W3C has to deal with.
Working on higher quality presentation of 3-D information is still under development. The W3 Consortium is trying to enhance the web to fulfill the requirements of global communities that include all regional languages and writing systems.
Work on privacy and security is going on such as hiding information, accounting, access control and integrity and risk management.
As there is a huge growth in field of web, it leads to overload of internet and decrease its performance. Hence, much better protocol is needed for future.
