Updated May 21, 2026Reviewed by APScore5 Editorial Team
These AP CSP Unit 2 flashcards cover all 60 Data terms with two-sentence definitions—flip cards, shuffle, and review before the practice MCQ set.
Each card front shows a term you will see on MCQs; the back uses two sentences so the first line defines and the second adds an exam example or trap. Do not rush through all sixty in one sitting—twenty cards a night for three nights beats one tired pass where you confuse bit and byte.
Shuffle when you return to a deck you already saw. Fixed order feels easier only because your brain memorized position, not meaning. After a miss on the practice set, search this deck for the tag (binary, compression, metadata, big data) and redo ten related cards before reopening MCQs.
Terms cluster naturally: place values and bit width sit near bytes and file-size units; compression ratio sits near RLE and lossy format names; EXIF and PII sit near metadata and re-identification. When a back mentions a guide, open that link the same evening while the card is still fresh.
Every 5th card shows a short ad placeholder with a 3-second delay, matching other unit decks.
How many AP CSP Unit 2 flashcards are on this page?
There are sixty cards covering binary, bits and bytes, compression, metadata, and big-data terms including privacy and bias. Each card flips to a two-sentence explanation aligned to AP CSP Unit 2 Data.
What topics do the Unit 2 flashcards cover?
Cards span representation (bit, byte, binary places), compression methods and formats, metadata, PII, re-identification, and data bias. They match the concept guides linked from the Unit 2 Guide.
Should I shuffle the flashcard deck?
Yes. Shuffling breaks order-based memorization. Use the shuffle button before a second pass so terms appear in mixed order like exam questions.
How long does the full deck take?
Most students spend twenty to thirty minutes for one careful pass. Shorter daily slices of fifteen to twenty cards often stick better than one long cram session.
What order should I study flashcards versus guides?
Read a concept guide first when a term is new, then use flashcards for recall. If class already covered the unit, run cards before the eighteen-question quiz or fifty practice MCQs.
Can I use flashcards on my phone before class?
The deck works in mobile browsers—tap to flip, use the arrow for next. Pair phone sessions with at least one desktop pass through practice MCQs.
What if I forget a card after flipping?
Mark the term, open the matching concept guide from the hub, and retry that card tomorrow. Repeated misses mean you need MCQs, not more flipping alone.
Do flashcards include lossless and lossy examples?
Yes. Cards contrast ZIP, PNG, JPEG, MP3, and RLE where AP CSP expects format vocabulary. Sort scenarios without reading hints before you take the quiz.
Are these official AP CSP terms?
Definitions follow College Board Unit 2 Data wording used on APScore5 guides. They are study aids, not a copy of secure exam items. Compare unclear terms with your teacher or AP Central.
What should I do after finishing all sixty cards?
Take the eighteen-question Unit 2 quiz, then the fifty practice MCQs. Flashcards build recognition; quizzes and practice build application.
