APCSP quiz 2/11 With 100% complete
solution A+ rated
Binary data - correct answer ✔✔Data is "either/or" or "yes/no". There are only two possible
outcomes
what data types does Boolean represent? - correct answer ✔✔binary data, logical values. ex:
true or false, on or off, yes or no
text compression - correct answer ✔✔The act of reducing the size of a file.
Lossy Compression - correct answer ✔✔A process for reducing the number of bits needed to
represent something in which some information is lost or thrown away. This process is not
reversible.
Lossless Compression - correct answer ✔✔a data compression algorithm that allows the
original data to be perfectly reconstructed from the compressed data.
Sound compression - correct answer ✔✔uses a compressor which detects a signal exceeds a set
threshold and then attenuates it by a specified amount, effectively squishing the dynamic range
of the audio signal
1 byte - correct answer ✔✔8 bits
4 bits - correct answer ✔✔1 nibble
values of a 4 bit configuration - correct answer ✔✔0-15
