AP Computer Science Principles EXAM Quizlet Question and Answer 2023.
Overflow Correct Answer: error that results when the number of bits is not enough
... [Show More] to hold the number, like a car's odometer "rolling over"
Round-off Correct Answer: error that results when the number of bits is not enough to represent the actual number, like 3 digits to represent π as 3.14
Lossy Correct Answer: Compressing data in a way that throws some data away and makes it almost impossible to recover the original, great compression, like JPEG images
Lossless Correct Answer: Compressing data in a way that preserves all data away and allows full recovery of the original, good compression -- usually not as good as lossy, like PNG images
Metadata Correct Answer: data about data, like a camera storing the location, aperture, shutter speed, etc. for a digital photo
Sequencing Correct Answer: code flows line by line, one after another, like a recipe
Selection Correct Answer: a boolean condition to determine which of two algorithmic paths are taken, aka if-then
Iteration Correct Answer: using a looping control structure, like while, for, foreach, repeat, repeat-until, etc.
Reasonable Time Correct Answer: polynomial in the number of steps an algorithm takes in the worst case based on the input size
Not reasonable time Correct Answer: Usually exponential in the number of steps, like doubling every time your input grows by one
Heuristic Correct Answer: using a "rule" to guide an algorithm, like always walking toward the north star if you were stuck in a forest
Undecidable Correct Answer: A problem that is so difficult, we can't ever create an algorithm that would be able to answer yes or no for all inputs, like determining if a user's program run on some input would always stop and not run forever
Linear Search Correct Answer: Going one by one vs starting in the middle and going left/right like looking for a word in the dictionary
Binary Search Correct Answer: requires the list to be sorted in order and then cutting the list in half
APIs Correct Answer: Application Programming Interface
Citizen Science Correct Answer: Lots of people to help with a scientific project, like asking everyone around the world to count the butterflies they see one day
Cloud Computing Correct Answer: Using distributed calculations and/or storage for big data or a web application
Crowdsourcing Correct Answer: Asking lots of users online to help with something, like funding a project, or running SETI@Home to help look for extraterrestrial signals [Show Less]
