I don't think you can answer the question of what something actually is.
Our perception of reality is based around making models that simplify what is actually going on. This is how science works, but it is also how our brain understands the vast amount of information it receives. People struggle to understand whether a photon is a particle or a wave. It is actually neither, but both models are useful in making predictions about how it will propagate.
Someone can use a computer, and get repeatable testable results on the screen for a given set of inputs. They do not need to look inside the computer.
