What is a Uniform Resource Locator (URL)?
A Uniform Resource Locator (URL) is a unique identifier used to locate a specific resource on the internet. It contains information about the protocol used to access the resource, the domain name, and sometimes the path to the resource. URLs are used to access web pages, images, videos, documents, and other files.
Components of a URL
A URL is made up of several components, including:
- Protocol: The protocol used to access the resource (e.g. http, https, ftp, etc.)
- Domain Name: The domain name of the server hosting the resource (e.g. example.com)
- Path: The path to the resource (e.g. /path/to/resource)
- Query String: A set of key/value pairs used to pass data to the resource (e.g. ?key=value&key2=value2)
Examples of URLs
Here are some examples of URLs:
- http://example.com – A web page on the example.com domain.
- https://example.com/images/logo.png – An image on the example.com domain.
- ftp://example.com/files/document.pdf – A file on the example.com domain.
- http://example.com/?q=search+term – A web page on the example.com domain with a query string.
Conclusion
URLs are an essential part of how the internet works, as they provide a way to locate and access resources on the web. URLs are made up of several components, including the protocol, domain name, path, and query string. Examples of URLs include web pages, images, files, and resources with query strings.
