3. 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 • Anything out of date in this chapter?

4. What’s the Deal With That Pesky For Loop?? for ( INIT ; TEST ; NEXT) { BODY} INIT NEXT 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! TEST? yes BODY no

5. 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

6. Examples of Employers of UMBC Computing Majors • Booz Allen Hamilton • Northrop Grumman • Lockheed Martin • Care First Blue Cross Blue Shield • NSA • T Rowe Price • IBM • General Electric Finance Read Student Alumni Profiles at: http://www.careers.umbc.edu/profiles/ View Career Services & Shriver Calendar at: http://www.careers.umbc.edu/news_events/calendar.php

25. 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

26. Project Teams • Get into your new teams and come up with answers to these questions: • Find one thing that you all have in common. • Find one thing that’s different for all of you (the answer “we all have different names” does not count!) • 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!
