its at an extremely high pressure

You've got a couple good answers already, which are intimately related. The very high density of matter in the core of the Earth is so dense because of the forces of gravity which are compressing it to the point where it retains its solid behavior. The same materials at lower pressures are liquid at the same temperatures.

There is a lot of pressure. The whole weight of the Earth is right on the core due to the inner core's gravity. The pressure prevents the mass from melting.

Same reason water boils at a lower temperature at higher altitudes...Water boils at 212 F. at sea level...Reduce the pressure and boiling temp goes down...Increase the pressure, like in a pressure cooker, and the boiling temp goes up..
Same with the earth's core which is under a lot of pressure...

The inner core is not solid. The inner core is surrounded by insulating matter (earth, rock, etc.)

Because of gravity.

Gravity from the core pulls everythingb in and that is why it is solid. I don't know why it is hot but I think gravity has got to do with it also....

Don't count on my answer. It's just my theory.

I assume you mean the Earth.

The immense pressure of gravity squashes it into a solid ball

b/c it has too much pressure on it and is composed of the highest density materials

very high external pressure

I think it is made of magma
