Please help the moderator, what does this mean

Header (' Www-authenticate:basic realm = ' realm-name ');
Header (' status:401 unauthorized ');
Header (' http/1.0 401 Unauthorized ');
Header ("location:http://www.example.com/");
Header (' www-authenticate:negotiate ');
Header (' WWW-AUTHENTICATE:NTLM ', false);

What is the use of this message?

This sentence is sent to the browser, with JS can be obtained.
You can pass a string to the browser. I didn't use that much either.
