Introduction of World Wide Web
World Wide Web Overview
WWW stands for World Wide Web. A technical definition of the world wide web is : all the resources and users on the internet that are using the Hypertext Transfer Protocol (HTTP).A more expansive definition is provided by the World Wide Web Consortium (W3C), an organization co-founded by Tim Berners-Lee, the inventor of the Web. According to the W3C, the World Wide Web encompasses a vast network of accessible information, serving as a representation of collective human knowledge. Put simply, it serves as a means of exchanging information among computers connected to the internet, linking them together to form an extensive repository of interactive multimedia resources. Internet and web and the internet are not synonymous; rather, the web utilizes the internet as a medium for transmitting and sharing information.
The inception of the World Wide Web dates back to 1989 when Timothy Berners-Lee, while working at CERN in Geneva, formulated a proposal with the aim of facilitating effective collaboration among researchers. This proposal evolved into what we now know as the World Wide Web.
WWW works on client- server approach. Following Steps explains how the web works:
When user enters the URL say, https://www.genuinetech.pk of the web page in the address bar of web browser.
Then browser requests the Domain Name Server for the IP address corresponding to www.genuinetech.pk.
Once the browser acquires the IP address, it proceeds to send a request for the web page to the web server, utilizing the HTTP protocol that defines the communication method between the browser and the web server.
Then web serve receives request using HTTP protocol and checks its search for the requested web page. Upon locating the requested information, it is then returned to the web browser, and subsequently, the HTTP connection is closed.
Once the web page is received by the browser, it proceeds to interpret the page and presents the contents within the window of the web browser for display.
The field of web development has experienced rapid advancements, leaving a profound impact on various sectors including education, research, technology, commerce, and marketing. The far-reaching influence of the web makes its future largely unpredictable. Alongside the significant progress in the World Wide Web, the W3 Consortium faces the challenge of addressing various technical issues that arise.
