When we are typing something in search box of Google, many suggestions are presented in the drop dowa box. This in managed using which technology?

The correct answer is Option 3) Ajax.

Key Points

• Ajax (Asynchronous JavaScript and XML) is the technology used to fetch data asynchronously from the server without reloading the page.
• When you type something in the Google search box, Ajax sends a request to the server with the typed characters.
• The server processes the request and sends back suggestions based on the input.
• The browser then updates the dropdown suggestion list dynamically — all without refreshing the web page.
• This technique improves user experience by making web applications faster and more interactive.

Additional Information

• Option 1 – React: A JavaScript library for building user interfaces. It can work with Ajax but does not handle AJAX inherently.
• Option 2 – Angular: A framework for dynamic web applications that also supports AJAX, but it is not specific to this autocomplete functionality.
• Option 4 – DHTML: Refers to a collection of technologies (HTML, CSS, JavaScript), but it doesn’t handle asynchronous requests like Ajax.
• Ajax Tools: XMLHttpRequest (older method), Fetch API (modern method), and third-party libraries like Axios or jQuery Ajax.
