Web browsers are software for accessing the internet, displaying websites via HTML, CSS, and JavaScript. Popular ones include Chrome, Firefox, Safari, and Edge. They support tabs, bookmarks, and extensions.

Web Browsers

A web browser is a software application used to access and view websites on the internet. Browsers retrieve information from web servers and display it on your device. They are essential tools for navigating the vast amount of information available online.

Web Browsers Working

1. URL Entry: When you type a web address (URL) into the browser’s address bar and press Enter, the browser begins its work.
2. DNS Lookup: The browser converts the web address into an IP address through a process called DNS (Domain Name System) lookup.
3. Server Request: Using the IP address, the browser sends a request to the web server hosting the site.
4. Data Retrieval: The server processes the request and sends back the website’s data, typically in HTML, CSS, and JavaScript formats.
5. Rendering: The browser then processes this data to display the website on your screen.

Key Features of Web Browsers

1. Address Bar: This is where you type the URL of the website you want to visit.
2. Search Engine Integration: Most browsers allow you to search directly from the address bar or have a separate search box.
3. Bookmarks: You can save your favorite websites for quick access later.
4. Tabs: You can open multiple web pages in the same window using tabs, making multitasking easier.
5. History: Browsers keep a record of the websites you visit, allowing you to revisit them easily.
6. Extensions/Add-ons: These are small software programs that add extra features to the browser, such as ad blockers or password managers.

2. Browser Engine: Bridges the interface and the rendering engine.
3. Rendering Engine: Interprets HTML, CSS, and JavaScript to display web pages.
4. Networking: Manages network calls, such as HTTP requests.
5. JavaScript Engine: Executes JavaScript code to make web pages interactive.
