An instruction to communicate across a network
|
Detailed explanation-1: -Web browsers communicate with web servers using the HyperText Transfer Protocol (HTTP). When you click a link on a web page, submit a form, or run a search, the browser sends an HTTP Request to the server.
Detailed explanation-2: -Each website has a unique address, called a URL (short for Uniform Resource Locator). It’s like a street address that tells your browser where to go on the Internet. When you type a URL into the browser’s address bar and press Enter on your keyboard, the browser will load the page associated with that URL.
Detailed explanation-3: -HTTP is the most widely used protocol for web browser and web server communication, but there are other protocols that are used as well. For example, the Secure Hypertext Transfer Protocol (HTTPS) is used for secure communication between web browsers and web servers.
Detailed explanation-4: -The web browser will then obtain the IP address of the domain name–either translating the URL through DNS (Domain Name System) or by searching in its cache. This will bring the browser to a web server. The browser will then request the specific file from the web server by an HTTP request.
Detailed explanation-5: -A client (a browser) sends an HTTP request to the web. A web server receives the request. The server runs an application to process the request. The server returns an HTTP response (output) to the browser. The client (the browser) receives the response.
