Web Browser in a Nutshell:
A web browser is like a translator for the internet. It takes HTML, CSS, and JavaScript code (the languages of the web) and turns it into the websites you see and interact with.
Key components:
- Rendering engine: Interprets code and displays content.
- Networking: Connects to servers and fetches data.
- User interface: Provides controls for navigation, browsing, and interaction.
- Security: Protects you from malicious websites and code.
Popular browsers
- Arc,Chrome, Firefox, Safari, Edge, Opera
How it works
CLIENT-SERVER MODEL
- You type in a website address (URL).
- The browser sends a request to the server hosting the website.
- The server sends back the website’s code. (HTTP/HTTPS)
- The browser renders the code into the website you see.
- You interact with the website using the browser’s interface.
In short: A web browser is your window to the internet, allowing you to access and interact with the vast world of web content.
