Abstraction

Question 1

Abstraction

Answer 1

the process of extracting or distilling the underlying essence

Question 2

bits

Answer 2

stored binary information declared by voltages above 0.5 and below 0.5

Question 3

a voltage of one is equal to a bit? T or F?

Answer 3

True

Question 4

Levels of Abstraction

Answer 4

higher abstraction is more broad and simple

Question 5

top down design

Answer 5

the designing of tasks starting with a higher level of abstraction rather than lower

Question 6

what are the 2 Design Goals?

Answer 6

correctness & efficiency

Question 7

correctness

Answer 7

software works as inteneded; any input produces the desired output. NO CRASHES

Question 8

efficiency

Answer 8

not having to wait. time efficiency

Question 9

3 implementation goals:

Answer 9

Robustness, adaptability, reusability RAR!

Question 10

robustness

Answer 10

correct output for all inputs; handles unexpected inputs

Question 11

adaptability

Answer 11

should be used for along time; software should evolve through simple modifications

Question 12

Reusability

Answer 12

we should be able to use the same code as components of different software apps.; timesaver

1. atomic data (ints, floats, chars)
2. arrays
3. structure types

Question 15

T or F: data organization follows implementation principles

Answer 15

True ; organization is key.
