URL part: the web page or file name

The last part of a URL. It names the web page or file wanted: folders (the path) then the file name, like shoes.html. With no file name, the server sends a default page.

Understanding URL part: the web page or file name in IGCSE Computer Science Paper 1

What it does: The extension after the dot tells the browser what type of file is wanted, and .html means a web page. The folders images and logos make up the path, and school.png is the file name at the end. If no file name is given, the web server sends a default page, usually the site's home page. The URL names the file, and the web server holds it. The protocol (http or https) only says how to request it.

Common mistakes: URLs separate folders and the file name with forward slashes (/), not backslashes. It should be https://a.com/men/hat.html. The file name includes its extension. The file name is toys.html, not just toys.

Quick Questions

1. In https://www.shop.com/products/shoes.html, which part names the page wanted?

A. https://www.shop.com

B. /products/shoes.html ✓

The final part of the URL, after the domain name, gives the path and file name of the page wanted. The start is the protocol and domain.

2. In /products/shoes.html, what is 'products'?

A. A folder in the path ✓

B. The file name

Folders make up the path. The file name comes last, so here it is shoes.html.

3. Which one is the file name in /products/shoes.html?

A. shoes.html ✓

B. /products/

The file name is the very last item in the URL. /products/ is the path of folders leading to it.

4. What does the .html extension at the end of shoes.html tell us?

A. The file is stored on the user's computer

B. The file is a web page written in HTML ✓

The extension shows the file type. .html means a web page. The file itself is stored on the web server.

5. A user types https://www.shop.com with no file name. What happens?

A. The server sends a default page, such as the home page ✓

B. The server sends back an error every time

If no file name is given, the web server sends a default page, usually the site's home page.

Match the Pairs

/products/shoes.html → The path and file name at the end of a URL: the products folder, then the web page shoes.html

https://www.shop.com/ → A URL with no file name, so the server sends the site's default page, such as index.html

The file extension .html shows the file is a web page → about.html

Folders in the path are separated by / and come before the file name → /images/logos/school.png

https://www.shop.com/products\shoes.html → A backslash was used in the path. Folders in a URL are separated by forward slashes, so it should be /products/shoes.html.

https://www.shop.com/shoes html → The file name has a space and no dot, so the extension is missing. It should be shoes.html with a dot before html.

Spot the Error

Question 1

A https://a.com\men\hat.html

B Domain: a.com

C Path: /men/

D File name: hat.html

Line A — URLs separate folders and the file name with forward slashes (/), not backslashes. It should be https://a.com/men/hat.html.

Question 2

A https://a.com/kids/toys.html

B Protocol: https

C Path: /kids/

D File name: toys

Line D — The file name includes its extension. The file name is toys.html, not just toys.

Question 3

A https://a.com/

B No file name is given

C Server sends a default page

D Often named index.com

Line D — A default page is a web page file such as index.html. .com is a domain ending, not a file extension for a web page.

Question 4

A url = a.com/shop/cart.html

B folder = shop

C file = shop

D ext = html

Line C — shop is the folder (part of the path). The file name is the last part, so it should be file = cart.html.

Question 5

A https://a.com/music/rock.html

B Path: /rock.html

C File name: rock.html

D Extension: .html

Line B — The path is the folder, which is /music/. rock.html is the file name, not part of the path.
