can someone explain left outer join and right outer join better? or just give a better example.

I understand that they only take the data from either from the right table or left table including the similar column/data. but I didn't really get the example that they used. from what I understand from both examples is that they could be the same answer??

in left outer join the table benefits d leftmost column i.e it gives d non-matched values also instead of only matching ones...n thus, vice versa in right outer join
