What type of beer is hoppy?

I'm curious, could you tell me more about what type of beer is described as being hoppy? Is it a specific style or a characteristic that can be found in multiple styles of beer? What are the defining features of a hoppy beer, and what sets it apart from other types of beer? Additionally, are there any particular brewing techniques or ingredients that contribute to a beer's hoppiness? I'm eager to learn more about this aspect of beer appreciation.
