"Cómo" means "how" in english, while "Qué" means "what". However, we are not used to say "¿qué es tu nombre?" but "¿cuál es tu nombre?" The literal translation of "¿Cómo te llamas?" would be "How are you named", but I think it sounds weird in english :p

What=que How=como We in this case “what is” as “cual es”.... not every translation is literal... there a few things you just have to learn. :) hope it helps!

That is one of the difficult parts of learning a language. I'm learning Russian by myself and I realize that every language has its own structures. At the beginning it is hard to understand, but once you begin to think in the logic of that language, it becomes easier. So, in Spanish we just say "¿Cómo te llamas?" (literaly "how do you call yourself?") or "¿cuál es tu nombre?" ("which is your name?"). "¿Qué es tu nombre?" for us that sounds like "what (thing) is your name?" I hope that helps.
