"PDF" (Portable Document Format) is a format that allows you to read electronic documents, either on or in a format you can print out on your home computer. This format provides a page-by-page view of documents, exactly as they appear in their printed form, and lets you search for information in the document using keywords. Adobe provides a free Acrobat Reader that allows you to view, navigate, and print PDF files across all major computing platforms. If you do not already have it, you may download the FREE Adobe Acrobat reader, which you may then install and use to access your PDF courses.
