When you search any terms on the browser, it displays various<strong> websites or links,<\/strong> but before this, it goes through various steps like the interpretation of HTML codes.<\/p>\n<p>Every browser has its own interface, but the <strong>root structure<\/strong> is the same for all browsers. Knowing the steps before you actually tap on a link or after this is really stimulating.<\/p>\n<p>Web browsers follow <strong>tens of loops<\/strong> to display the results, but we got them in less than a second!

Webkit provided the foundation for most <strong>browsers, even Chrome<\/strong>, but at a later stage, all browsers are ported to <strong>macOS, iOS, Linux, Microsoft Windows<\/strong>.<\/p>\n<p>To understand how does a browser work, one must be enlightened about the <strong>components of a browser<\/strong> to make the browser work. Following are the 7 essential components of web browsers:<\/p>\n<ol>\n<li>User interface.<\/li>\n<li>Browser engine.<\/li>\n<li>Rendering engine.<\/li>\n<li>Networking.<\/li>\n<li>UI Backends.<\/li>\n<li>JavaScript interpreter.<\/li>\n<li>Data storage.<\/li>\n<\/ol>\n<h2><span class=\"ez-toc-section\" id=\"Important_components_of_browser\"><\/span><strong>Important components of browser<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: center;\"><img decoding=\"async\" class=\"aligncenter wp-image-1110 size-full\" src=\"https:\/\/basicwebguide.com\/wp-content\/uploads\/2022\/02\/Browsers-main-components-34.png\" alt=\"How does a browser work\" width=\"448\" height=\"254\" srcset=\"https:\/\/basicwebguide.com\/wp-content\/uploads\/2022\/02\/Browsers-main-components-34.png 448w, https:\/\/basicwebguide.com\/wp-content\/uploads\/2022\/02\/Browsers-main-components-34-300x170.png 300w, https:\/\/basicwebguide.com\/wp-content\/uploads\/2022\/02\/Browsers-main-components-34-20x11.png 20w\" sizes=\"(max-width: 448px) 100vw, 448px\" \/><\/p>\n<h3><span class=\"ez-toc-section\" id=\"1_User_Interface\"><\/span><strong>1. User Interface<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The user interface is the view on which a user <strong>first interacts<\/strong> while opening the browser. Although it is not a <strong>direct component for working<\/strong> a web browser, it is mandatory for user engagements.<\/p>\n<p>The user interface includes an address bar, search bar, back and forward button, bookmark, history, downloads, etc.<\/p>\n<p>We can say UI is the interaction medium between <strong>humans and machines<\/strong>. Better the user interface design, the greater the user engagement and effectiveness of the browser.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_Browser_Engine\"><\/span><strong>2. Browser Engine<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The browser engine is the <strong>chief component<\/strong> of a browser, and the entire working of the browser is much more dependent on this. The major function of a browser engine is to <strong>transmute HTML documents<\/strong> and other assets of a web page into an <strong>interactive visual portrayal<\/strong> on a user&#8217;s device.<\/p>\n<p>In other words, the browser engine works as the bridge between the user interface and the rendering engine. In most browsers, the browser engine is<strong> blink or JavaScript<\/strong>.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"3_Rendering_Engine\"><\/span><strong>3. Rendering Engine<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A rendering engine is software that displays text, images, and specific output requested by the user. The rendering engine <strong>extracts text<\/strong> from the <strong>HTML codes, CSS, or other popular documents<\/strong> as well draws the format to be displayed. Some popular rendering engine includes <strong>Redshift, Blink, Webkit, Gecko, etc<\/strong>.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"4_Networking\"><\/span><strong>4. Networking<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Networking connects<strong>\u00a0the web browser<\/strong> interface and rendering engine with the Internet. This is done via the various internet components like <strong>HTTPS, TCP, IP, data links, DNA lookups, etc.,<\/strong>\u00a0and displays the result in the prescribed user interface.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"5_UI_Backend\"><\/span><strong>5. UI Backend<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>As the name suggests, the UI backend works in the back end and <strong>won&#8217;t interpret by users<\/strong> (usually) while opening the browser. It also manages the basic widgets or windows of the browser like <strong>select box, input box, check box, and windows<\/strong>.<\/p>\n<p>However, UI backend structure entirely depends on the structure, <strong>HTML code, and CSS codes of that browser<\/strong>.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"6_JavaScript_Interpreter\"><\/span><strong>6. JavaScript Interpreter<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>JavaScript interpreters read and <strong>interpret the JavaScript code,<\/strong> including every line of the entire code. Earlier, the browsers used the above method to read JavaScript, but in modern technology, <strong>JavaScript compiles all the codes<\/strong> and executes them immediately using Just-in-Time methods.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"7_Data_Storage\"><\/span><strong>7. Data Storage<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>All the above-discussed documents, layout, structures, components like <strong>HTML codes, texts, etc.,<\/strong> are stored in the data storage file of the browser.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_does_a_browser_work-2\"><\/span><strong>How does a browser work?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: center;\"><img decoding=\"async\" class=\"aligncenter wp-image-1112 size-full\" src=\"https:\/\/basicwebguide.com\/wp-content\/uploads\/2022\/02\/Screenshot-2022-02-15-232913.jpg\" alt=\"How does a browser work\" width=\"631\" height=\"370\" srcset=\"https:\/\/basicwebguide.com\/wp-content\/uploads\/2022\/02\/Screenshot-2022-02-15-232913.jpg 631w, https:\/\/basicwebguide.com\/wp-content\/uploads\/2022\/02\/Screenshot-2022-02-15-232913-300x176.jpg 300w, https:\/\/basicwebguide.com\/wp-content\/uploads\/2022\/02\/Screenshot-2022-02-15-232913-20x12.jpg 20w\" sizes=\"(max-width: 631px) 100vw, 631px\" \/><\/p>\n<p>Until we discuss what a browser is and its main components, this is the time to know <strong>how a browser works<\/strong>. We can most commonly say a <strong>web browser works<\/strong> by combining all the above-discussed components.<\/p>\n<p>When a web browser <strong>requests information<\/strong> from a worldwide web source, it utilizes a <strong>rendering engine<\/strong> to convert the data into text and pictures. Web browsers interpret this code to construct what we see, perceive and <strong>interact with on the Internet,<\/strong>\u00a0written in <strong>Hypertext Markup Language (HTML)<\/strong>.<\/p>\n<p>When you enter a <strong>URL (Uniform Resource Locator)<\/strong> into the browser&#8217;s address bar, it retrieves HTML files comprising <strong>photos, PDFs, videos, and other content<\/strong>. Following the steps proceeds when we enter a URL on a browser:<\/p>\n<ul>\n<li>The browser must first determine the web server&#8217;s <strong>IP address.<\/strong><\/li>\n<li>The IP address is found via <strong>DNS record,<\/strong> stored in the router and ISP cache.<\/li>\n<li>Now, the browser\u00a0initiates a<strong class=\"ht fz\"> TCP connection<\/strong> with the server.<\/li>\n<li>The browser sends an <strong>HTTP GET request<\/strong> to the webserver as per the HTTP specifications.<\/li>\n<li>Browsers quickly start to <strong>comprehend and render<\/strong> the HTML file as a response and simultaneously retrieve the items, displaying the messages and elements obtained.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Final_Thoughts\"><\/span><strong>Final Thoughts<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>It is all about <strong>how does a browser work<\/strong> and I hope you like this easy and detailed guide on browser&#8217;s working.
