Where does it come from?

I've taken a few short, but compact, classes before. I'm starting over because I have lost almost everything. My question is is that when I type something in whatever code I'm using. what is telling it to do what I'm typing. What is the underlying code that makes it so my code works or doesn't based on what I type?

When you type in a shell with whichever language you are writing in, the interpreter expects patterns of text that match that language. It Reads what you type, Evaluates, Prints the result and Loops back to start again. What I think you're wondering is what drives it all. For that we can thank Ada Lovelace and her analytical engine. Maybe too general an answer, but feel free to add to it everyone :)
