Confidentiality correct answer: In information security, confidentiality "is the property, that information is not made available or disclosed to unauthorized individuals, entities, or processes" Integrity correct answer: In information security, data integrity means maintaining and assuring the accuracy and completeness of data over its entire life-cycle. This means that data cannot be modified in an unauthorized or undetected manner. This can be also used to validate databases to make s...

Algorithm efficiency typically measured by the algorithm's computational complexity Computational complexity the amount of resources used by the algorithm. The most common resources considered are the runtime and memory usage. runtime complexity a function, T(N), that represents the number of constant time operations performed by the algorithm on an input of size N Space-complexity (of an algorithm) a function, S(N), that represents the number of fixed-size memory units...
