Computer Architecture Review quiz answers Basic concepts you should know CPU and its two parts, the controller and the ALU Storage – different types and differences in terms of speed, capacity, volatility, and cost Input and output How it all works together Questions? Anything out of date in this chapter?

What’s the Deal With That Pesky For Loop?? for ( INIT ; TEST ; NEXT) { BODY } Your for loop always, always, always must have this form – you can put different things for INIT, TEST, NEXT, and BODY, but the rest has to look just like this! INITNEXT BODY TEST ? yes no

Movie Day Computer History in 90 Seconds Names you should be familiar with World War II: ENIAC / “Top Secret Rosies” So why aren’t programmers primarily women any more? Careers in computer science From Columbia University Refers to CS, but Columbia doesn’t have Business Technology, IS, or Computer Engineering, so they’re really talking about Computing in general

Check Out A short history of software engineering: Long, rambling, not that interesting; funny for people in the field A brief history of software: Look at A glimpse and a hook – blog by Micheal Lopp Managing Humans Being Geek Video is dated Careers in computer science: Good, but very CS-centric and Columbia- centric Can be justified by explaining that Columbia ONLY has CS (also has EE but nothing else in IT) Computer Information Systems Careers: horrible Pathways in Computer Science: U DUB Cool examples – alums talk about their jobs – nicely done CS-centric, and UW has lots of of other IT programs IT manager job description: Not produced greatly, but accurate description of IS professional – a little dated, not as exciting as other videos on CS

The Point Each of you has declared a major of BTA, IS, CMSC, or CMPE You can change your major It’s better to change your major sooner rather than later We want to help you make the right choice for you If we do our jobs, you’ll have a much clearer idea of what major you want, what you can do with it, and why it’s right for you

Project Teams Get into your new teams and come up with answers to these questions: 1. Find one thing that you all have in common. 2. Find one thing that’s different for all of you (the answer “we all have different names” does not count!) 3. Pick a team name. (Maybe the answers to #1 and #2 will inspire you.) NOTE: For this and other team activities, any team member may be asked to present the answer to any question!
