In the process of viewing a web page, what is typically the first user action?

• A. Enter the URL
• B. Create an HTTP request
• C. Render the page
• D. DNS lookup

Answer: (A)

Entering the URL is the action that starts everything. When you type an address, you signal the browser to navigate to that page. After that, the browser handles the behind-the-scenes steps: it looks up the domain to find the server (DNS lookup), sends a request to fetch the page (an HTTP request), gets the response, and then renders the content for you to view. So the initial user action is typing the address, while DNS lookup, the HTTP request, and rendering happen after that request is initiated.
