What is a URL?
A URL stands for Uniform Resource Locator. It is the standard address used to locate a specific resource—such as a webpage, image, video, or file—on the internet.
Think of a URL as the internet's equivalent of a street address: just as a physical address tells you where to find a specific house in the real world, a URL tells your web browser where to find a specific file or page on a server.
Structure of a URL
A typical URL is made up of several key components:
https://www.example.com:443/path/to/page.html?query=value#section
-
Protocol (
https://): Specifies the communication protocol the browser should use to securely connect to the server (e.g.,httpsfor secure web traffic,httpfor unsecure, orftpfor file transfers). -
Domain Name (
www.example.com): The human-readable name of the server or website hosting the resource. It points to a specific IP address on the network. -
Port (
:443): An optional numerical gate used to access the server. Browsers usually hide this because standard ports are implied by the protocol (e.g., port 443 for HTTPS, port 80 for HTTP). -
Path (
/path/to/page.html): The specific directory and file location on the server. It directs the browser to the exact resource requested. -
Query Parameters (
?query=value): Optional data passed to the server, often used for searches, filters, or tracking (separated from the path by a question mark?). -
Fragment / Anchor (
#section): An optional identifier that points to a specific section or bookmark within the webpage (indicated by a hash#).
