Country codes show country origin: .in (India), .us (USA), .uk (UK), .pk (Pakistan), .jp (Japan), .fr (France).Example: www.harvard.edu

Extensions help users identify the site’s purpose and trust level.
High Complexity (Analysis & Scenario-Based) Q6. Your school Internet is very slow. You must read notices and download a small PDF quickly. Plan your approach and justify your browser choice.
Answer:
Use a text-based browser like Lynx for reading notices.
It loads only text , so pages open faster on slow Internet.
Use keyboard navigation to move through links and open the notice page.
For the PDF download , follow the link and let the file download.
If the PDF must be viewed, save it and read it in a PDF reader offline.
Avoid heavy images and videos to save data and time.
This plan combines speed with essential access .
It fits the goal: quick reading and a small download .
Q7. You need to show a science video with animations to your class. Which browser type will you choose and how will you prepare?
Answer:
Choose a GUI-based browser like Chrome or Firefox .
It supports videos , images , and animations .
Make sure the computer has enough CPU and bandwidth .
Open the video in a tab beforehand to test playback.
Close extra tabs to free resources and avoid lag .
Keep a bookmark as backup and check the volume and controls .
If the net is unstable, pre-load or use a local download if allowed.
This ensures a smooth and engaging class demo.
Q8. On the school website, you click “Email the Principal” and it opens your email app. Explain how the mailto URL works and compare it with http/https.
Answer:
The link uses the mailto scheme (like mailto:principal@school.edu ).
The browser sees mailto and opens your email application .
It fills the To field with the given email address .
There is usually no path like a web page in mailto links.
http/https load web pages from a web server using the Host/Domain and Path .https also means data is sent securely .So, mailto starts an email , while http/https fetch web content .
Both are protocols but serve different purposes .
Q9. Your browser blocks many pop-ups on a study site. Analyze the benefits and possible drawbacks. How should a student handle this?
Answer:
Pop-up blocking and ad filtering improve safety and focus .They stop annoying windows and reduce distractions .
Pages may load faster because fewer ads are loaded.
But sometimes, needed features (like login windows ) may be blocked.
The student can allow pop-ups for trusted sites only.
Use the browser’s site settings to make exceptions.
Keep passwords safe using the browser’s password manager .
Balance security with functionality for a better study experience.
Answer:
URL 1 uses https , which is generally more secure than http.
The Domain is nasa.gov . The .gov shows a government site (USA).
The Path shows a specific page about the station mission.
URL 2 uses http and the Domain is unesco.int .
The .int shows an international organisation .
The about path likely leads to an information page.
From the schemes, URL 1 is secure (https), URL 2 is not (http).
From the extensions, we learn the type and scope of each site.
