A URL, or Uniform Resource Locator, is the address used to access resources on the internet. It specifies the location of a resource and the protocol used to retrieve it.
A typical URL consists of several components:
1. **Protocol**: This indicates how data is transferred. Common protocols include:
- `http` (Hypertext Transfer Protocol)
- `https` (HTTP Secure)
- `ftp` (File Transfer Protocol)
2. **Domain Name**: This is the human-readable address of a website, such as `example.com`.
3. **Path**: This specifies the location of a resource on the server. For example, in the URL `http://example.com/folder/file.html`, `/folder/file.html` is the path.
4. **Query String**: This part, which starts with a `?`, allows you to send additional data to the server. For example, in the URL `http://example.com/search?q=keyword`, `q=keyword` is the query string.
5. **Fragment**: This starts with a `#` and refers to a specific section within a webpage. For instance, `http://example.com/page#section1` directs you to `section1` of the page.
An example of a complete URL is:
```
https://www.example.com/path/to/resource?query=parameter#section
```
In this example:
- `https` is the protocol.
- `www.example.com` is the domain.
- `/path/to/resource` is the path.
- `query=parameter` is the query string.
- `#section` is the fragment.
URLs are essential for navigating the web, allowing browsers to locate and fetch content from websites.
