Prefixes were applied to the word byte to represent different orders of magnitude. These chips, known as dual-core (two processors) or quad-core (four processors), increase the processing power of a computer by providing the capability of multiple CPUs all sharing the processing load. After completing this reading, think about how you use information systems in your everyday life. The definition or description of what defines a computer has changed.
