Sure, knowing that there's something out there to look for might be helpful. (Might not, too. Googling "how do I remove items from a list by priority" might get you info on priority queues.)

But if I know that "priority queue" is what I'm looking for, I can then totally forget how to implement a priority queue. I can look it up as many times as I'm going to need it in the rest of my career faster than I can memorize it. (And if I need it very many times, I'll memorize it just by using it.)
