AP COMPUTER SCIENCE PRINCIPLES FINAL EXAM
REVIEW 2026 100% PASS ASSURED UPDATED
EXAM SOLUTIONS.
Overflow - correct answer- error that results
when the number of bits is not enough 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
