John is trying to use a data abstraction in a program to finish the lab he is working on. What is the purpose of abstraction, and how does it fulfill its purpose?
Abstraction is a method of organizing data in a program so that it is easier to understand, access, and use the data. This is done by making a line of code that takes unformatted, raw data as an input, and stores that data in a specified, organized format, and by making more lines of code that can extract specific parts of this data for the programmer's desired purpose.
What is bandwidth and how is it usually measured?
Bandwidth is the maximum amount of data that can be sent in a fixed amount of time. It is measured in bits per second.
What is recursion?
Calling a procedure from inside itself.
Which real world example does not illustrate bias in AI programming development ?

Emma is writing a program that will draw a cupcake on a plate. She doesn't want the all the cupcakes the program draws to look the same, so she has the program choose a between 2 types (i.e. color, shape, size) of each component (i.e. frosting, cake, topping). Here is her code for her reporter, "frosting choice", which chooses between chocolate and vanilla frosting: If (pick random 1 to 5) = 3 report "vanilla"Elsereport "chocolate" Emma doesn't like the vanilla to chocolate ratio produced by her program. How can she increase the frequency at which the program chooses vanilla frosting?
