Goal: More Computer Parts and what they do... aka: Why is your computer slow? 

Do Now:
1. Evaluate:
a) (quotient (remainder 12 11) (remainder 5 3) )
b) ( / (- (* 3 2) 5) (* (- 3 2) 5) )

2. While you do those:
 Log into the HW server, and view the file you submitted (you can use guest if your account isn't ready yet)

Updates: 
Vocabulary Document was updated, important words are on the top so you don't have to memorize a bunch of the ones I won't ask you about. 
Quiz Friday

Go Over HW04:
Homework Solutions:
;1a.   
(+ (/ (- 5 (* 4 2)) (- 10 5) ) 3) 
;b.   
(+ 2 (/ (* 3 (- 4 2)) (- 1 (/ 3 5))))
;c.   
(- (/ (+ 4 (* 3 2)) (- 5 10)) 1)

;2a. 
 ( * (+ 4 -7 9) (/ 15 5) (- 3 -1) )
 (* 6 3 4)
 72
;b. 
 (/ (- 20 -4)   (* -3 2 -1))
 (/ 24 6)
 4


Why is your computer slow

If you ever feel like your computer is terrible, remember your computer is probably better than these:

Discussion about computer hardware based on that jargon document. 


Slow internet
Slow processor
Slow graphics
Slow hard disk
Slow ram (because you don't have enough)

Games: [5 minute discussion if we have time]

Computer science is about making games, like masonry is about making pizza. 
Someone has to design and build a brick oven (for real pizza) , but that doesn't mean that's the skill you should learn if you want to make pizza.
