Global Network Data Transmission Protocol Foundation The internet is a vast network of It enables data transmission The internet operates on a set of interconnected computers and through a complex infrastructure of protocols, including TCP/IP, which devices, allowing for cables, routers, and servers, govern communication between communication and information facilitating the flow of information devices and ensure data integrity. sharing worldwide. across continents. Communication Between Browsers & Servers Request The browser sends a request to the server, specifying the desired web 1 page or resource. Response 2 The server receives the request, retrieves the requested content, and sends a response back to the browser. Rendering 3 The browser receives the response, interprets the HTML, CSS, and JavaScript code, and displays the web page. Origins of the World Wide Web 1 1. Conceptualization 2 2. Initial Development Tim Berners-Lee, a British He developed the first computer scientist, web browser, editor, and conceptualized the World server in 1990, laying the Wide Web in 1989, while foundation for the web as working at CERN, a we know it today. research institute in Switzerland. 3 3. Public Release In 1991, the World Wide Web was publicly released, revolutionizing the way information was accessed and shared. Key Components of the World Wide Web Web Browsers Web Servers Software applications, such as Chrome, Firefox, and Powerful computers that store and deliver web pages to Safari, used to access and display web pages. browsers, enabling access to online content.
