Question: The sampling rate, (how many samples per second are stored) for a CD is...?
Correct Answer CDs reproduce 44,100 samples per second. Which has a maximum frequency reproduction of 22,050 Hz, or just a hair past the upper limit of human hearing. In this way CDs can theoretically reproduce any frequency in the human hearing range.
Question: Compact discs, (according to the original CD specifications) hold how many minutes of music?
Correct Answer According to many stories surrounding the origin of the compact disc, 74 minutes was settled on because it would comfortably contain all of Beethoven's 9th symphony on one disc. Although some stories reference a specific Sony higher-up who claimed this as his favorite piece of music, stories differ. All that's known for sure is that Sony insisted on this and won out over Phillips' original 60 minute proposal.
Question: The base 10 (or decimal - our normal way of counting) number 65535 is represented in hexadecimal as...?
Correct Answer Hexadecimal numbers use the characters 0-9 and A-F, where A = ten, B = eleven and so on. Each column is a power of 16 greater than the column to its right, with the rightmost column the one's column. The 0x at the start of the number indicates the number is in hexadecimal. This may seem obvious when the number has letters in it (such 0xFFFF) but a number like 32 decimal is represented as 20 hexadecimal so 0x20 is proper.
