first trip to the barbershop, what is this cut called?

I have never been to a barbershop. I have hair thats bout 4 in long and i've just been going to a family friend to get my haircuts but I want to try something new. I have cornrows and I want to shape my hairline and get the point my sideburns but to look like they are fading away. What is this type of haircut called?
