Urls are directions that browsers follow in order to find specific web page files. what is the first part of the url that is the standard system of commands that computers use to transfer information?

URLs (Universal Resource Locators) have several parts. The syntax is:

protocol://server.secondLevelDomain.topLevelDomain:portNumber/path/to/file?argument1=value1&argument2=value2

The portNumber isn't needed if you're connecting to the well known port of the protocol (for http port 80). If no protocol is given, browsers assume http.

Google 'climate change' and it will bring up tons of info and websites. its up to you which website you choose.
