    Mark-up Language

    it has been coded with "Tags" surrounding it which instruct various computers, with different operating systems, how to interpret the information such that it can be understood.

    HTML

    HyperText Markup Language is the code generated for WEB Pages.

    Professional programmers have made this job of constructing all these TAGs very simple for us. We use software known as a "generator" or "interpreter software" to do the dirty work for us. All we need to do is the tasks we are familiar with, what we do every day in "Word Processing".
