The graph on the left denotes a case where the timing attack is successfully able to detect a cached image whereas the one on the right is unable to do the same. In cryptography, a timing attack is a side-channel attack in which the attacker attempts to compromise a cryptosystem by analyzing the time taken to execute cryptographic algorithms.
Piano key frequencies. This is a list of the fundamental frequencies in hertz (cycles per second) of the keys of a modern 88-key standard or 108-key extended piano in twelve-tone equal temperament, with the 49th key, the fifth A (called A 4 ), tuned to 440 Hz (referred to as A440 ).
