Theory
Read an address like a postman
Chirag's nephew calls the shop: "Ma'am at school says type the U-R-L in the address bar. Which one is the URL? Is it just www dot something?"
You glance at the browser on the billing PC:
https://www.irctc.co.in/booking/train-list
Every piece of that line has a name and a job. Learn to read it like a postman reads an envelope, and browser questions become free marks.
Theory
A postal address for pages
A parcel needs: the delivery method (speed post), the building (a house address), and the exact flat number. A web page needs the same three: protocol (how to fetch it), domain (which site), path (which page inside the site). The whole line together, method + building + flat, is the URL: one page's complete postal address on the web.
Theory
Dissect the example
https:// www.irctc.co.in /booking/train-list
- https: the protocol, the rules for fetching the page; the S means secure (encrypted), shown as the padlock.
- www.irctc.co.in: the domain, the site's registered name. Read right to left:
.incountry (India),.cocommercial,irctcthe organisation,wwwthe traditional web prefix. - /booking/train-list: the path, which page within the site.
URL = all of it together. The domain is one part of the URL, not a synonym.
Theory
The cockpit around the page
- Address bar: the strip where URLs are typed. Modern browsers make it double as a search box: type words, get Google; type a URL, go directly.
- Links (hyperlinks): clickable text or images that jump to another URL. Links are the "web" in World Wide Web, pages woven together by them.
- Navigation buttons: Back (previous page), Forward (undo the back), Refresh/Reload (fetch the page again), Home (your set start page).
Quiz
In https://www.irctc.co.in/booking/train-list, which part is the domain?
- www.irctc.co.in
- https
- /booking/train-list
- The entire line
Show the answer
www.irctc.co.in
The domain is the site's name portion: www.irctc.co.in. The https is the protocol, /booking/train-list is the path, and the whole line is the URL. "Underline the domain in this URL" is a beloved one-mark exam item, and option D (calling everything the domain) is its favourite trap.
Think first
The padlock question
Your bank's site shows https and a padlock; a random blog shows plain http. What is the practical difference, and on which site would you type a password?
Show the answer
https encrypts the traffic between you and the site: anyone tapping the line sees scrambled data. Plain http travels readable. Passwords, OTPs and card numbers belong ONLY on https pages, which is why every bank, UPI app and exam portal uses it, and why browsers now warn loudly on http forms. One letter, whole answer.
Watch out
Where marks leak
Writing URL and domain as synonyms: the domain is a part of the URL. Expanding URL wrongly: it is Uniform Resource Locator. And a subtle one: the address bar is part of the browser, not part of the web page; label questions expect you to separate the browser's chrome (bars, buttons) from the page it displays.
Theory
A skill, not just vocabulary
Reading URLs protects you: sbi-secure-login.xyz.com is NOT SBI's domain (read right to left: the site is xyz.com). Phishing lives on students who cannot dissect an address. You now can. Next lesson finishes the subject with the browser's memory: tabs, bookmarks and history, the workflow tools of every study session.
Summary
Key takeaways
- URL = complete page address: protocol + domain + path.
- https = secure protocol (padlock, encrypted); the S protects passwords.
- Domain = the site's name, read right to left (.in country, .co commercial, irctc organisation).
- Address bar types URLs and searches; links weave pages into the web.
- Navigation: back, forward, refresh, home.
- Memory hook: method, building, flat, a postal address for pages.
