How it really works behind the [computer] screen.

I have always been fascinated with how things work, that includes the “virtual” how things work. From the users' point of view, everything that comes up on your screen of choice just feels like magic. You touch or click something on the screen and you get a response. You can touch or click that same spot and you might end up with something completely different. That's just amazing!! These things don’t happen in the physical world but in the virtual world, endless. This is what drives me to become an application developer. This is why I want to learn all there is to know about coding and what really does on behind the screen.
