Quiz
 Individual quiz: 5 minutes
 Team quiz: 5 minutes
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 Anything out of date in this chapter?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
}
INIT
NEXT
TEST
?
no
yes
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!
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
Examples of Employers of
UMBC Computing Majors
 Booz Allen Hamilton
 Northrop Grumman

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!
