11. Computer Vs Theater

13. CPU is fast: can do several performances at one time. CPU is dumb: no improvisation possible. Machine language much lower-level than programming language.

14. Why Java Modern, modular (object-oriented) language. Good Error Detection. Rich Library Embodying Many Good Programming Principles Can Write Teaching Tool (ObjectEditor)

15. Java Versions, Dialects & Programming Enviromnet JDK 1.1 Microsoft Implementation Swing 1.1 Visual J++ Programming Environment Will not matter
