How to Merge Two Columns of Data into One?

This one should be pretty simple, I just can't remember how to do it. Column A has all first names and column B has all last names. How do I merge the two into a single column that has both the first name form column A AND the last name from column B?

Thanks!

in cell c1 enter the following

=CONCATENATE(A1," ",B1)

You can also use the following in c1:

=a1 & " " & b1
