World Wide Web (www)

The World Wide Web (WWW) is known as the Web. It is a database infrastructure where documents and other web services are defined through Uniform Content Locators (URLs, such as https:/, which can be interlinked by hypertext, and are available across the Internet. Online services are transmitted using the Hypertext Transmission Protocol (HTTP), users may access a software application called a web browser and publish a software application called a web server. The World Wide Web is not associated with the Internet, which has been pre-existing the Web in any way for two decades and on which the Web is designed.

Tim Berners-Lee, an English astronomer, created the World Wide Web in 1989. He wrote his first web browser in 1990 while working at CERN near Geneva, Switzerland. The browser was published to other academic organizations outside CERN beginning in January 1991, and then to the general public in August 1991. The Web started to be used on a regular basis in 1993-4, when websites for general use began to become available. The World Wide Web has been central to the development of the Information Age and is the dominant means of connecting on the Internet used by billions of people.

Web services may be any kind of media accessed, but web pages are hypertext documents formatted in Hypertext Markup Language (HTML). Unique HTML syntax shows built-in hyperlinks with URLs that allow users to connect to other web services. Web pages can include, in addition to text, references to images, video, audio, and software components that are either displayed or executed internally in a user’s web browser to render multimedia content pages or streams.

Tim Berners-idea Lee’s of a global hyperlinked information system became a reality in the second half of the 1980s. By 1985, the global Internet had begun to proliferate in Europe, and the Domain Name Structure (on which the Standardized Resource Locator was built) was created. The first direct IP link between Europe and North America was formed in 1988, and Berners-Lee started to publicly explore the possibilities of a web-like structure at CERN. Berners-Lee grew dissatisfied by the inefficiencies and problems posed by finding information stored on multiple devices while working at CERN. On 12 March 1989, a memorandum, titled “Information Management: A Suggestion,” was sent to CERN for a system named “Mesh” and referred to ENQUIRE, a database and software project that it had developed in 1980, which used the word “internet” and defined a more elaborate information management system focused on links expressed as text: “Imagine, then that the references in this document are all found in this document.

The World Wide Web had many variations accessible at the time from other hypertext networks. Instead of bidirectional connections, the Network needed only unidirectional links, allowing anyone to connect to another resource without the owner of that resource behaving. The complexity of installing web servers and browsers (compared to earlier systems) was also substantially decreased, but the recurrent issue of link rot was presented in turn. The World Wide Web was non-proprietary, unlike contemporaries such as HyperCard, making it easier to freely build servers and clients and to add extensions without license constraints. CERN declared on 30 April 1993 that the Web would be open to all without charge of any fees. This caused a dramatic change away from Gopher and onto the Internet, two months after the announcement that the server version of the Gopher protocol was no longer free to use.

The Internet and World Wide Web  are commonly used without distinction. The two words, however do not mean the same thing. The Internet is a distributed infrastructure with integrated data networks. The World Wide Web, on the other hand, is a vast array of documentation and other tools connected by hyperlinks and URIs. Web services are accessed using HTTP or HTTPS, which are application-level Internet protocols that employ Internet transport protocols.

Viewing a web page on the Web usually starts either by entering the URL of a page in a web browser or by clicking on a hyperlink to that page or resource. The web explorer then initiates a sequence of background communication messages to download and view the requested page. In the 1990s, using a browser to access web pages and switch from one web page to another via hyperlinks came to be known as ‘browsing,’ ‘web surfing’ (after channel surfing), or ‘online browsing.’ Early observations of this emerging behavior examined usage habits in the usage of web browsers. One research, for example, found five consumer patterns: exploratory surfing, window surfing, advanced surfing, bounded navigation, and targeted navigation.

The web browser scans the HTML and interprets the markup (<title>, <p> for paragraph, and so on that surrounds the words to format the text on the page. Many web pages use HTML to link to URLs of other services, such as images, other embedded media, scripts that affect page actions, and Cascading Style Sheets that affect page layout. The browser sends additional HTTP requests to the web server for these other forms of Internet media. As the contents are received from the web server, the browser can gradually view the page on the screen as defined by its HTML and these additional tools.

A website is a set of linked online services, including web sites, interactive material, normally labeled with a generic domain name, and hosted on at least one web server.

A web browser (commonly referred to as a browser) is a consumer software agent for viewing information on the Web. The user must have a web explorer application to connect to the web server and view its pages. This is a software that the user is running to import, format and view a web page on the user’s device.

A Web server is a server program or hardware devoted to running the software that can fulfill World Wide Web client requests. In general, a web server can contain one or more websites. The web server handles incoming network requests via HTTP and many other similar protocols.

A web cache is a cloud device placed either on the public Internet or inside a corporation that holds previously viewed web sites to increase the response time for users when the same material is requested within a specified amount of time after the initial request. Many web browsers often use a window cache to write recently acquired data to a local data storage unit.

Methods for viewing the Internet in alternative platforms and formats are in order to promote the use of people with disabilities. These disorders can include visual, auditory, physical, speech-related, emotional, psychological, or a combination. Accessibility features can benefit those with transient injuries, such as fractured limbs, or elderly users as their skills alter. The Network gathers information, offers information and communicates with society.
