A Crossword Puzzle on Simulation Definitions and Fundamentals

Read/View   Before beginning this Home Mini Exam, be sure you have viewed and read the following items from Week 1 of the Course Syllabus:

• View Videotape 1 (Course Outline and Overview) 

• View Videotape 2 (Fundamental Definitions of Systems Simulation) 

• Read: Chapter 1, pp. 3 - 20 in text Discrete-Event System Simulation (3rd Edition)

The Puzzle:  You may print the puzzle and the clues in either of two ways:

a) Print a hard copy of this web page

b) Click anywhere on the Crossword Puzzle grid below to obtain a PDF file (which may be read in the freely available Adobe Acrobat Reader)  containing both the Crossword Puzzle and the clues.

Submit: The puzzle with your filled in answers. Be certain to print CLEARLY, on your submitted puzzle, your last name, first name, and Student ID. Submissions may either be hand-delivered to Dr. Scher (Room 4407 GITC, slide under door if he is not in the office), or snail-mailed (must be postmarked on or before the due date - no exceptions) to Dr. Julian M. Scher, Department of Information Systems, College of Computing Sciences, New Jersey Institute of Technology, 323 Dr. Martin Luther King Jr. Blvd., Newark, NJ 07102).
