👉 Browsers, such as Google Chrome, Mozilla Firefox, and Safari, perform computing tasks primarily through their web browsers' built-in engines. These engines handle various aspects of web content processing, including rendering web pages, executing JavaScript, managing network requests, and handling security protocols like HTTPS. When a user visits a website, the browser's engine fetches the HTML, CSS, and JavaScript files from the server, parses them to construct the document structure, and then renders the visual elements on the screen. Additionally, browsers employ caching mechanisms to store frequently accessed data locally, improving performance and reducing load times. They also implement security measures like Content Security Policy (CSP) to protect against malicious attacks, and utilize various APIs to interact with web services and enhance user experience.
