This list of 'keywords' is intended to help you study for exams. Please note, however, that most of the questions on exams in this course are designed to test your understanding of and ability to apply concepts, not your ability to define words. However, being familiar with the meanings of these terms will help you understand the language used in exam questions. Also, a review of these terms may serve as a mental checklist of topics covered.
