Essentially, a web browser is your gateway to the internet, enabling you to navigate and interact with the vast amount of data available online.
Here are some key functions and components of a web browser:
Key Functions of a Web Browser
1. Navigation:
• Address Bar: Users can enter URLs (Uniform Resource Locators) directly to navigate to specific websites.
• Search Functionality: Most browsers have integrated search engines that allow users to perform web searches directly from the address bar.
2. Rendering:
• HTML Parsing: Browsers interpret HTML (HyperText Markup Language) to display web pages correctly.
• CSS Application: Browsers apply CSS (Cascading Style Sheets) to style and layout web pages.
• JavaScript Execution: Browsers execute JavaScript to add interactivity and dynamic content to web pages.
3. User Interface:
