The Language module provides detection and selection rules. By default, the module will detect the current language based on the URL, with the language code acting as a prefix to the current path. For example, /es/node will display the node listing page in Spanish, as seen in the following screenshot:

You can have multiple detection options enabled at once and use the ordering to decide which takes precedence. This can allow you to use the language code in the URL first, but, if they are missing, a fallback to the language is specified by the user's browser.

Some detection methods have settings. For instance, the URL detection method can be based on the default path prefix or subdomains.
