AP COMPUTER SCIENCE PRINCIPLES
FINAL EXAM REVIEW EXAM 2025/2026
QUESTIONS AND ANSWERS 100% PASS.
Overflow - ANS error that results when the number of bits is not enough to hold the number,
like a car's odometer "rolling over"
Round-off - ANS 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 - ANS 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 - ANS 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 - ANS data about data, like a camera storing the location, aperture, shutter speed,
etc. for a digital photo
Sequencing - ANS code flows line by line, one after another, like a recipe
Selection - ANS a boolean condition to determine which of two algorithmic paths are taken,
aka if-then
