Computer question from Laboratory Attendant exam, 2026 by JKSSB
Which of the following options best explains how a web browser loads a webpage when a user enters a URL?
Last updated Jun 19, 2026
Correct Answer:
Option C —
DNS finds the IP and HTTP/HTTPS loads the page
How it works step-by-step:
DNS Resolution: When you type a URL (like www.example.com), the browser cannot navigate to a text name. It first asks the Domain Name System (DNS)—the phonebook of the internet—to translate that domain name into a numerical IP address (like 192.0.2.1).
HTTP/HTTPS Request: Once the browser has the IP address, it uses HTTP or HTTPS (the secure version) to send a request to the web server at that IP address.
Rendering: The web server sends back the website's files (HTML, CSS, JavaScript), which the browser then renders into the webpage you see.
Why the other options are incorrect:
A) Browser downloads the page directly from the ISP: Your Internet Service Provider (ISP) just provides the pipeline/connection to the internet; they do not host or store the webpages themselves.
B) SMTP resolves the name and transfers the webpage: SMTP (Simple Mail Transfer Protocol) is used exclusively for sending emails, not for loading web pages.
D) The search engine fetches and renders the page: A search engine (like Google) helps you find URLs, but once you enter a URL into the address bar, the browser communicates directly with the hosting web server, completely bypassing the search engine.
