(WWW) World Wide Web known as the Web, is an information space where documents and other web resources are identified by Uniform Resource Locators,which may be interlinked by hypertext, and are accessible over the Internet.The resources of the WWW may be accessed by users by a software application called a web browser.Web resources may be any type of downloaded media, but web pages are hypertext media that have been formatted in Hypertext Markup Language (HTML).Multiple web resources with a common theme, a common domain name, or both, make up a website. Websites are stored in computers that are running a program called a web server that responds to requests made over the Internet from web browsers running on a user's computer.
The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide.It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies.
when a user use the domain name like (www.google.com) the request is sent to the server with the ip address of the domain name then the server receive the request and return the wanted data in a http response.
The Web platform is a collection of technologies developed as open standards by the World Wide Web Consortium and other standardization bodies such as The Web Hypertext Application Technology Working Group, the Unicode Consortium, the Internet Engineering Task Force, and Ecma International. It is the umbrella term introduced by the World Wide Web Consortium.The Web platform includes technologies—computer languages and APIs—that were originally created in relation to the publication of Web pages.
(HTTP) Hypertext Transfer Protocol , is an application protocol for distributed, collaborative, hypermedia information systems.It is the foundation of data communication for the World Wide Web.
(URL) Uniform Resource Locators (also called a web address) is a reference to a resource that specifies the location of the resource on a computer network and a mechanism for retrieving it. A URL implies the means to access an indicated resource, which is not true of every URI. URLs occur most commonly to reference web pages (http), but are also used for file transfer (ftp), email (mailto), database access (JDBC), and many other applications.
(HTML) HyperText Markup Language,is the standard markup language used to create web pages. It describes the structure of a website semantically along with cues for presentation, making it a markup language, rather than a programming language.
(CSS) Cascading Style Sheets is a style sheet language used for describing the look and formatting of a document written in a markup language, used to change the style of web pages and user interfaces written in HTML and XHTML or to any kind of XML document, including plain XML, SVG and XUL.
(DOM) Document Object Model is a cross-platform and language-independent convention for representing and interacting with objects in HTML, XHTML, and XML documents. The nodes of every document are organized in a tree structure, called the DOM tree. Objects in the DOM tree may be addressed and manipulated by using methods on the objects.
JavaScript is a high level, dynamic, untyped, and interpreted programming language. It has been standardized in the ECMAScript language specification.JavaScript is prototype-based with first-class functions, making it a multi-paradigm language, supporting object-oriented, imperative, and functional programming styles. It has an API for working with text, arrays, dates and regular expressions, but does not include any I/O, such as networking, storage or graphics facilities, relying for these upon the host environment in which it is embedded.
(JSON) JavaScript Object Notation , It is the primary data format used for asynchronous browser/server communication (AJAJ), largely replacing XML (used by AJAX). Although originally derived from the JavaScript scripting language.It is currently described by two competing standards, RFC 7159 and ECMA-404. The ECMA standard is minimal, describing only the allowed grammar syntax, whereas the RFC also provides some semantic and security considerations. The official Internet media type for JSON is application/json. The JSON filename extension is .json.
Web Content Accessibility Guidelines (WCAG) & Accessible Rich Internet Applications (ARIA)
Accessibility refers to the design of products, devices, services, or environments for people with disabilities.The concept of accessible design ensures both “direct access” (i.e., unassisted) and "indirect access" meaning compatibility with a person's assistive technology.
