AP CSP COMPUTER SCIENCE CORE EXAM SET 2026/2027
QUESTIONS AND SOLUTIONS RATED A+
✔✔Public Key Encryption - ✔✔Used prevalently on the web, it allows for secure
messages to be sent between parties without having to agree on, or share, a secret
key. It uses an asymmetric encryption scheme in which the encryption key is made
public, but the decryption key is kept private.
✔✔Digital Divide - ✔✔the gulf between those who have ready access to computers and
the Internet, and those who do not.
✔✔Hypothesis - ✔✔A proposed explanation for some phenomenon used as the basis
for further investigation.
✔✔Search Trends - ✔✔Comparison of the popularity of topical queries in an online
search engine as they relate to time.
✔✔Visualization - ✔✔Images, diagrams, tables, etc created from information extracted
from a given data set, with the express intention of highlighting a data story.
✔✔Pivot Table - ✔✔The name of the tool used by most spreadsheet programs to create
a summary table.
✔✔README - ✔✔A document providing background information about a dataset.
✔✔CSV - ✔✔Abbreviation of "comma-separated values," this is a widely-used format
for storing data.
✔✔Raw data - ✔✔The original data as it was collected.
✔✔Summary table - ✔✔A table of aggregate information about a dataset (e.g., the
average, sum, count of some values).
✔✔Filter - ✔✔tool/technique using dynamic parameters for reducing a data set to
viewing only similar items in a row or column.
✔✔Aggregation - ✔✔A computation in which rows from a data set are grouped together
and used to compute a single value of more significant meaning or measurement.
Common aggregations include: Average, Count, Sum, Max, Median, etc.
✔✔Binary question - ✔✔a question where there are only two possible answers
✔✔Protocol - ✔✔A set of rules governing the exchange or transmission of data
between devices.
, ✔✔ASCIII - ✔✔The universally recognized raw text format that any computer can
understand
✔✔American Standard Code for Information Interchange - ✔✔What does ASCII stand
for? (cap first letter)
✔✔code - ✔✔(slang) to write instructions for a computer
✔✔Redundancy - ✔✔repetition of information or the inclusion of additional information
to reduce errors in transmission.
✔✔DNS - ✔✔The service that translates URL's to IP addresses
✔✔Domain name service - ✔✔DNS stands for...
✔✔HTTP - ✔✔the protocol used for transmitting web pages over the internet
✔✔Hypertext transfer protocol - ✔✔HTTP stands for...
✔✔TCP - ✔✔provides reliable, ordered and error checked delivery of a stream of
packets in the internet
✔✔URL - ✔✔an easy to remember address for calling a web page
✔✔Octal - ✔✔The octal number system is base 8, using only digits 0 through 7.
✔✔Decimal - ✔✔Traditional number system using digits 0-9.
✔✔Iterative innovation - ✔✔Incremental or small improvement to an item
✔✔Novel innovation - ✔✔Improvement that is new, creative and has not been done
before "outside the box thinking."
✔✔Vint Cerf - ✔✔Internet pioneer who believed the Internet should be free and
available to everyone
✔✔Higher lower - ✔✔__________ level protocols use _______ levels without needing
to understand precisely how they work. (space between each term)
✔✔Lower higher - ✔✔_________ level protocols guarantee __________ level protocols
will function without stating specifically how this will be accomplished.
