A URL (Uniform Resource Locator) is a string used to uniquely identify and locate the address of a resource on the Internet or another network. A URL typically consists of several parts that specify various information about the resource:
-
Protocol: The protocol specifies how the resource should be accessed or transferred. Common protocols include HTTP (Hypertext Transfer Protocol), HTTPS (HTTP Secure), FTP (File Transfer Protocol), and FTPS (FTP Secure).
-
Hostname: The hostname identifies the server where the resource is hosted. This can be a domain like "example.com" or an IP address indicating the exact location of the server.
-
Port (optional): The port is a numerical address on the server that allows access to specific services. Default ports are often used implicitly (e.g., port 80 for HTTP), but custom ports can also be specified for special services.
-
Path: The path specifies the location of the resource on the server. It can refer to a specific directory or file.
-
Query string (optional): The query string is used to pass additional parameters to the server that can be used to identify or customize the requested resource. The query string starts with a question mark and usually contains a series of key-value pairs separated by the ampersand (&).
Together, these parts of a URL form the complete address of a resource on the Internet or another network. URLs are used in web browsers, hyperlinks, APIs, and other internet applications to access and identify resources.
