documents
(DOCX, PDF, or JPG) is NOT a common computer format to scan - ANS-DOCX
^ - ANS-and, only true when both statements are true
<-----> - ANS-biconditional, only true when TT or FF

per second while 2 GHz means two billion ticks per second

light - ANS-digital light processing projector

the individual propositions that occur in it - ANS-contradiction
a compound proposition is a ______ if the proposition is always true, regardless of the
truth value of the individual propositions that occur in it - ANS-tautology

A CPU accesses 100 program instructions. Each memory access takes 5 nanoseconds
(ns, or billionths of a second). All 100 instructions are in memory. What is the total time?
- ANS-500 because 100 instructions * 5 ns/instr= 500 ns
A CPU accesses 100 program instructions. Each memory access takes 5 ns. The
memory can only hold 50 instructions. The first 50 instructions are already in memory.
Replacing those 50 by the next 50 takes 400 ns. What is the total time? - ANS-50 instrs
* (5 ns / instr)
+ 400 ns
+ 50 instrs * (5 ns / instr)
= 250 + 400 + 250
= 900 ns.
A CPU can access an item from cache faster than from memory (T or F) - ANS-true-
typically a cache access requires just 1 clock tick, whereas a memory access may
require multiple ticks like 4, 6, or even 10

size chip becomes higher speed
, a optical mouse detects movement by - ANS-comparing successive photos of the
surface below
a portable PC; smaller/lighter than a desktop PC, using less electrical power, and
operable from battery power - ANS-laptop

a touchscreen can be used effectively with a finger, pen, stick, and many other objects
(true or false) - ANS-false- touchscreens are designed to work with human skin
a touchscreen is a touch sensitive device layered on top of a display (true or false) -
ANS-true
A typical college student is about 20 years old. About how many times more capacity
does an IC have versus when the student was born, assuming capacity doubles every 2
years? - ANS-20 years has 10 doublings. 210 is 1,024. In a college student's short
lifetime, IC's became about 1,000 times better.
