What are AP CSP Unit 2 flashcards?
AP CSP Unit 2 flashcards are vocabulary cards that help students recall the key Data unit terms before applying them in quiz and practice questions. A strong Unit 2 deck should include binary, bits, bytes, compression, lossless versus lossy compression, metadata, big data, PII, privacy risks, re-identification, and data bias.
In one sentence: AP CSP Unit 2 flashcards help you turn Data vocabulary into fast recall before quiz and practice questions.
How to use these AP CSP Unit 2 flashcards
Use these flashcards in three passes. First, flip through the deck by topic so you understand each term. Second, shuffle the deck to break order-based memorization. Third, mark weak terms and open the linked concept guide before returning to quiz or practice questions.
Do not use flashcards as your only study method. Flashcards build vocabulary recall, but AP CSP questions usually ask you to apply terms to scenarios.
| Study Mode | Best Use |
|---|---|
| Learn by topic | When terms are new |
| Shuffle mode | When you already reviewed once |
| Weak-term mode | When you keep missing the same terms |
| Before quiz | Quick warm-up |
| After practice | Repair missed vocabulary |

AP CSP Unit 2 flashcard study plan
Use the deck as a spaced-repetition tool. A single fast pass is not enough. The goal is to recall the term, explain an example, and then apply it in quiz or practice questions.
| Time | Task |
|---|---|
| 5 minutes | Review only weak terms |
| 10 minutes | Run one topic filter |
| 15 minutes | Shuffle all terms and mark misses |
| 30 minutes | Full deck pass plus weak-term review |
Quick recall check
| Prompt | Expected Term |
|---|---|
| Smallest unit of digital information | Bit |
| 8 bits | Byte |
| Base-2 number system | Binary |
| Changing binary to base 10 | Binary-to-decimal conversion |
| Reducing file size | Compression |
| Keeps all original data | Lossless compression |
| Removes some data | Lossy compression |
| Data about data | Metadata |
| Data that identifies a person | PII |
| Anonymous-looking data linked back to a person | Re-identification |
| Incomplete or unrepresentative data | Data bias |
| Large, complex, fast, or varied datasets | Big data |
If you miss more than three terms, filter the deck by topic. If you miss two or fewer, take the Unit 2 quiz or full practice set.

Frequently asked questions
What flashcards should I study for AP CSP Unit 2?
Study binary, bits and bytes, binary-to-decimal conversion, compression ratio, lossless versus lossy compression, metadata, big data, PII, re-identification, and data bias. This deck has sixty cards with AP-style examples and links to concept guides.
How many AP CSP Unit 2 flashcards are on this page?
There are sixty flashcards in this deck, grouped by topic filters. Each card shows a term on the front and a definition plus exam example on the back.
Are these AP CSP Unit 2 flashcards like Quizlet?
Similar format—flip cards for recall—but these cards use AP CSP wording, two-part explanations, topic tags, and links to APScore5 practice and concept guides on the same site.
Should I use flashcards before or after Unit 2 notes?
Use notes or concept guides first when a term is new. Use flashcards for recall before the Unit 2 quiz or fifty practice questions. Return to notes only for terms you still miss.
Are flashcards enough for AP CSP Unit 2?
No. Flashcards build vocabulary but AP CSP items are scenario-based. Pair this deck with the Unit 2 quiz and full practice set to apply terms under pressure.
What are the hardest AP CSP Unit 2 terms?
Students often miss compression ratio versus percent saved, lossless versus lossy file picks, metadata privacy risks, PII, re-identification, and explaining both a benefit and a risk of big data.
Should I shuffle the AP CSP Unit 2 flashcards?
Yes, after one topic-filter pass. Shuffling breaks order-based memorization and better matches mixed exam questions.
What should I do if I keep missing the same term?
Tap Review again to add it to weak-term mode, open the linked concept guide, then rerun a short weak-term session before quiz or practice.
What should I do after finishing the flashcards?
Take the Unit 2 quiz, then the fifty practice MCQs. Use the cheat sheet for last-minute formulas and the review page for full explanations if you still miss topics.
Are these official AP CSP test answers?
No. These are original APScore5 study flashcards, not official AP CSP test answers or secure classroom assessment answers. Use them to build vocabulary recall, then practice with original AP-style questions.
