Q.Visit NCERT, SWAYAM or any other website and note down URLs of some of the specific pages of that website.

Website URL Structure: A First Look

Think of a URL — the web address you type into a browser — as a postal address for a house. A postal address tells the postman which country, city, street, and finally which specific building you mean. A URL does the same for a webpage: it tells the internet's system exactly where a particular page lives and how to get there.

The Everyday Intuition

You already use URLs every time you click a link or type something like www.example.com/about. That string of characters is not random. It is a carefully structured path that a web browser follows, step by step, to fetch the right page from the right computer somewhere in the world. Without this structure, the internet would be a chaos of unlabeled files — you would have no way to reliably find anything.

The Precise Meaning

A URL (Uniform Resource Locator) is the full address of a resource on the web. It has several parts, each with a specific job. Here is the general form:

protocol://domain-name/path/filename

Let us break that down piece by piece.

1. Protocol — The "How"

The protocol tells the browser how to communicate with the server. The most common one is https:// — the 's' stands for 'secure', meaning the data sent between you and the website is encrypted. Older or simpler sites might use http:// (without the 's'). You almost always see this at the very start of a URL.

2. Domain Name — The "Where"

The domain name is the human-readable name of the website. For example, in www.amazon.in, the domain is amazon.in. It is what you type into the address bar to reach a site. The domain name itself has sub-parts:

• Subdomain (optional): The www part is the most common subdomain. Some sites use blog.example.com or shop.example.com to separate different sections.
• Second-level domain: The main name, like amazon or google.
• Top-level domain (TLD): The suffix, like .com, .org, .in, .edu. This often hints at the type of organisation or country.

3. Path — The "Which Page"

After the domain comes the path, which tells the server which specific page or file you want. It looks like a folder structure on a computer. For instance:

https://www.example.com/products/laptops

Here, /products/laptops is the path. It suggests that inside a folder called products, there is a subfolder or file called laptops. The path can be several levels deep.

4. Filename (Optional)

Sometimes the path ends with an actual filename, like index.html or about.html. Often, if no filename is given, the server automatically serves a default file (usually index.html or index.php). So https://www.example.com/about/ might actually load https://www.example.com/about/index.html.

5. Query String (Optional)

You have probably seen URLs with a ? followed by extra text, like:

https://www.example.com/search?q=laptop&color=black

Everything after the ? is the query string. It sends extra data to the server — in this case, a search term (q=laptop) and a filter (color=black). The & separates multiple pieces of data. This is how search forms and filters work on websites.

6. Fragment (Optional)

A # at the end of a URL points to a specific section within a page. For example:

https://www.example.com/help#contact
``` …
