So can  someone help me eunderstand in a layman terms what is the meaning of

By writing this:

public PageReference test() { 
return something; 
}

you define the return type of the is function which is page reference.

Pagereference is used if you want to redirect the current page to another page.
 

Refer this documentation or more details : Pagereference Class

In below example you will find we have defined a new Pagereference variable newPage with url of google, and we use that variable for redirecting with returning it.

public PageReference test() {
PageReference newpage = new PageReference('http://www.google.com'); 
newpage.setRedirect(true); 
return newpage; 
}
