Hopefully… In the future, you know how to apply what you have learned in this class: Write good software Design a good system Analyze a complicated system Understand other’s work

My Advices Don’t put all your eggs in one basket Even a Ph.D. shouldn’t confine himself/herself in an Ivory Tower by just working on very narrow topics Who knows what will be the hot topics 5 years from now? Always look at the big picture Try to connect the big picture with your job functions.

Conclusion Over the last 50+ years computer architecture is a rapidly changing Science and engineering Hardware and software Consider this a historical course which took you to visit the key architecture concepts and designs in the history of computers. The more you know, the more tools in your box when you need to solve a problem. No need to invent new wheels. What is also important is to learn the way problems were solved. Your success at work has a lot depend on your problem solving skills and methodology.
