computational thinking

Question 1

abstraction

Answer 1

removes unnecessary details from the problem while keeping all relevant and importants peices of details

Question 2

advantages and disadvantages of abstraction

Answer 2

adv:
reduces processing requirements
reduces memory requirements
simplifies programming

disadv:
reduces scenery,sound and diagrams are not to scale

Question 3

thinking ahead

Answer 3

planning inputs, outputs and reusable components

Question 4

benefits and drawbacks of caching

Answer 4

storing instructions in RAM allows for faster use in future
can be complicated to implement

Question 5

the need of reusable components

Answer 5

use of classes
use of subprograms/subroutines
use of external libraries

Question 6

thinking procedurally

Answer 6

breaking the problem down(decomposition)

Question 7

thinking logically

Answer 7

identifying decision points for branching or iteration

Question 8

advanteages of thinking logically

Answer 8

determine time complexity of an algorithm

Question 9

thinking concurrently

Answer 9

identifying if parts of the program can be solved simultaneously

Question 10

advantages and siadvantages of thinking concurrently

Answer 10

speeds up solution
Less idle time for processor

may be difficult to program

Question 11

pipelining

Answer 11

looks for processes that can be processed simultaneously
processes are sequential
parallel processing
