Computer ArchitectureReview quiz answers
Basic concepts you should knowCPU and its two parts, the controller and the ALUStorage – different types and differences in terms
of speed, capacity, volatility, and cost Input and outputHow 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Anything out of date in this chapter?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!
INIT NEXT
BODYTEST?
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 scienceFrom Columbia UniversityRefers to CS, but Columbia doesn’t have Business
Technology, IS, or Computer Engineering, so they’re really talking about Computing in general
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

CMPE
The PointEach 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 TeamsGet 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!
