The cpu controls the speed at which the computer processes information. The primary factor in this speed is the cpu's processing chip. Another important factor in a computer's speed is the amount of its random access memory (ram). Ram is where your computer temporarily stores information being used by programs it's currently running.
Gao published a guide to assist its auditing staff in ensuring the reliability of computer-based data. The guidance provides a flexible, risk-based framework for data reliability assessments that can be geared to the specific circumstances of each engagement. The framework is built on (1) making use of all existing information about the data; (2) performing at least a minimal level of data testing; (3) doing only the amount of work necessary to determine whether the data are reliable enough.
