Every year or two, the capacities of computer hardware have approximately doubled inexpensively. This remarkable trend often is called Moore’s Law, named for the person who identified it, Gordon Moore, co-founder of Intel—the leading manufacturer of the processors in today’s computers and embedded systems, such as smartphones, appliances, game controllers, cable set-top boxes and automobiles.
Moore’s Law and related observations apply especially to
• the amount of memory that computers have for running programs and processing data
• the amount of secondary storage ...
