Adobe InDesign is a program used to take work that you have finished in either Photoshop or Illustrator, and position blocks of text and pictures while laying it out onto paper. This program can be used for so many different things such as a brochure, newspaper, books, business cards, virtually anything that involves huge amounts of text. The difference between InDesign and other programs is that InDesign excels in multi page layouts for projects, where with Photoshop or Illustrator, you are limited to only one page with multiple layers.
