The location of a resource on the internet is given by its Uniform Resource Locator (URL). A URL is essentially the address of a specific location on a computer network, such as the web, and it specifies both the location of the resource and the mechanism to retrieve it
. A URL typically consists of several parts:
- Protocol : Defines how the resource is accessed (e.g., HTTP, HTTPS, FTP).
- Domain name or IP address : Specifies the server where the resource is hosted.
- Path : Indicates the specific location or file on the server.
- Optionally, URLs can include port numbers, query parameters, and fragments to point to specific parts of a resource
For example, in the URL http://www.example.com/index.html
:
http
is the protocol,www.example.com
is the domain name,index.html
is the path to the resource on the server
Thus, the URL serves as the standardized way to locate and access resources on the internet.
