What trio of components is typically required to access a web page successfully?

• A. A web server, a web browser, and a URL
• B. An email server and client
• C. An FTP server and client
• D. A database server and client

Answer: (A)

To access a web page, three parts work together: a web browser, a web server, and a URL. The URL is the address that tells the browser which page to fetch. The browser uses that address to send an HTTP or HTTPS request to the web server that hosts the page. The server responds by sending back the page’s files—HTML, CSS, images, and scripts—and the browser renders them into the view you see. Without the browser, you can’t render the content; without the server, there’s nothing to serve; without the URL, there’s no address to fetch from. The other options involve services used for email, file transfer, or databases, which aren’t how web pages are delivered.
