74
What is the formal definition of an algorithm
A well ordered collection of unambiguous and effectively computable operations that when executed produces a result and halts in a finite amount of time
75
What does well ordered mean
When you finish one step, you know which one to do next (NOT SEQUENTIAL OR CONSECUTIVE)
76
What does unambiguous mean
You know exactly what they're asking of you... well defined
77
What is a computing agent
The person or thing that is carrying out the algorithm
78
What does effectively computable mean
doable
79
What does executed mean
Carried out
80
Why is it important that an algorithm produces a result
or else there is no point to the algorithm
81
Why is it important that an algorithm produces a result in a finite amount of time
So that the program will eventually produce results and not continue forever
82
Is something like a thermostat that is running forever, an algorithm?
No, it needs to be finite. It’s a program, which has an algorithm running within it.
83
What was the benefit to using GUI
It is easier to use than the command line interface
84
What is a WIMP(relation to GUI)
WINDOWS ICONS MENUS POINTERS
85
What is a good way to approach solving problems in computer science?
Break problems into smaller problems that would be more simple to solve (top down approach).
86
What is a top-down approach
“A top-down approach (also known as stepwise design) is essentially the breaking down of a system to gain insight into the sub-systems that make it up. In a top-down approach an overview of the system is formulated, specifying but not detailing any first-level subsystems.”
87
What is a pre-test
A pre-test conditional statement checks the continuation condition BEFORE executing the body of the conditional. A pre-test is also called a ZERO OR MORE TIMES test.
88
What is a post test
A post-test conditional statement executes the body of the conditional BEFORE testing the continuation condition. A post-test is also called a ONE OR MORE TIMES test.
89
What is a continuation condition
Boolean expression whether the body should be executed (whether the loop should continue or not).
90
What are the three primitive operations used to create an algorithm on the test
Get values for Set variable to Print
91
What was the name of the technique Kim from TASK showed us
The pomodoro technique (5 mins break to 20 mins study etc)
