SELECT empid, firstname + N' ' + lastname AS fullname

Is Query 1 the same as Query 2?

What is the role of N in Query 2?  Does it have something to do with using non-English characters in the last name?
Query 1:
SELECT empid, firstname + ' ' + lastname AS fullname
FROM HR.Employees;

Query 2:
SELECT empid, firstname + N' ' + lastname AS fullname
FROM HR.Employees;
