For complete details about what courseware is, refer to this link:
Basically, courseware is something that your prof feels is required in addition to your text. This can be, for example, print out of all your lab manuals, additional readings, which are photocopied from other texts etc. You can buy this from titles with your book if it is required for your course. Also note that the courseware cannot be returned unlike the textbooks, so make sure you will be staying in the course before buying the courseware
