The difference between labels and text boxes?

Labels are used as headings for things that are created when the system is. Text boxes start as empty boxes that people can type into when a program is running. If you have ever filled out a form on the internet, you type your information into text boxes and beside the text boxes are labels telling you what to type into them, like your name or address. You cannot type into the labels themselves, just into the text boxes. You'll have done all of this when you were entering in this question.
