BU415 Chapter Notes - Chapter 5: Silicon Dioxide, Flash Memory, Microprocessor
Document Summary
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 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 off from a device. Nonvolatile memory storage that retains data even when powered down (flash memory, hard disk) Flash memory non-volatile, chip-based storage, often used in mobile phones, cameras, and. Mp3 players; slower than conventional ram but holds its charge even when the power goes out. Solid state electronics semiconductor-based devices; 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 drives but hard drives are not. Semiconductor a substance such as silicon dioxide used inside most computer chips that is capable of enabling as well as inhibiting the flow of electricity.
