Document Summary
Chapter 5: moore"s law and more: fast, cheap computing, disruptive innovation, and what. Moore"s law: chip performance per dollar doubles every eighteen months. Microprocessor: the part of the computer that executes the instructions of a computer program. Random-access memory (ram): the fast, chip-based volatile storage in a computing device. Volatile memory: storage (such as ram chips): that is wiped clean when power is cut from a device. Nonvolatile memory: storage that retains data even when powered down (such as flash memory, hard disk, or dvd storage) Flash memory: nonvolatile, chip-based storage, often used in mobile phones, cameras, and mp3 players, sometimes called flash ram, flash memory is slower than conventional ram, but holds its charge even when the power goes out. Solid state components often suffer fewer failures and require less energy than mechanical counterparts because they have no moving parts. Ram, flash memory, and microprocessors are solid state devices.
