For example, [www.google.com](http://www.google.com) consists of host's machine name www and the domain name google.com.

#### Path

The path identifies the specific resource within the host that the user wants to access. For example, /search/flutter, /flutter/flutter-sdk-setup/, etc.

#### Scheme

The scheme identifies the protocol to be used to access the resource on the Internet. The scheme names followed by the three characters :// (a colon and two slashes). The most commonly used protocols are http\://, https\://, ftp\://.
