Binary Tournament Selection

My understanding of a tournament selection is:

For a given tournament size, t , randomly select t individuals from the population and determine the winner of that tournament as the individual with the largest fitness function value.

My question is:

Is there a difference between 'Binary Tournament Selection' and 'Tournament Selection', or are they interchangeable terms?

You have a value, lets call it k which determines of how many candidates you pick the best one for each parent you want to chose. This value is often 2 and in this special case we can also call it binary tournament selection. Tournament selection is just the broader term where k can be any number >= 2
