AP Computer Science Principles Exam with all Correct &
100% Verified Answers |Actual Complete Update |
Already Graded A+
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
Not reasonable time ✔Correct Answer-Usually exponential in the number of steps, like
doubling every time your input grows by one
Heuristic ✔Correct Answer-using a "rule" to guide an algorithm, like always walking toward
the north star if you were stuck in a forest
Undecidable ✔Correct Answer-A problem that is so difficult, we can't ever create an
algorithm that would be able to answer yes or no for all inputs, like determining if a user's
program run on some input would always stop and not run forever
, Linear Search ✔Correct Answer-Going one by one vs starting in the middle and going
left/right like looking for a word in the dictionary
Binary Search ✔Correct Answer-requires the list to be sorted in order and then cutting the list
in half
APIs ✔Correct Answer-Application Programming Interface
Citizen Science ✔Correct Answer-Lots of people to help with a scientific project, like asking
everyone around the world to count the butterflies they see one day
Cloud Computing ✔Correct Answer-Using distributed calculations and/or storage for big data
or a web application
Crowdsourcing ✔Correct Answer-Asking lots of users online to help with something, like
funding a project, or running SETI@Home to help look for extraterrestrial signals
Creative Commons ✔Correct Answer-An alternative to copyright that allows people to declare
how they want their artistic creations to be shared, remixed, used in noncommercial contexts,
and how the policy should propagate with remixed versions
Open Access ✔Correct Answer-A policy that allows people to have read access to things, e.g.,
libraries or online data
Moore's Law ✔Correct Answer-The # of transistors on a chip doubles every two years
Peer-to-peer Networks ✔Correct Answer-A system where one user's computer connects
through the Internet to another user's computer without going through an intermediary
"centralized" computer to manage the connection
Digital Divide ✔Correct Answer-The idea that some communities / populations have less
access to computing than others
ISP ✔Correct Answer-Internet Service Provider
How does internet communication arrive at its destination? ✔Correct Answer-Speech on the
Internet goes from the source to an ISP, into the cloud, out of the cloud to another ISP, and to its
destination
How can the government control speech on the Internet? ✔Correct Answer-1) It can try to
control the speaker or the speaker's ISP, by criminalizing certain kinds of speech. But that won't
work if the speaker isn't in the same country as the listener.
