Moore"s law: chip performance per dollar doubles every 18 months. Result of the (cid:862)faste(cid:396) a(cid:374)d (cid:272)heape(cid:396) (cid:272)o(cid:373)puti(cid:374)g(cid:863) phe(cid:374)o(cid:373)e(cid:374)o(cid:374) 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.

Ram inside our laptops is an example of volatile memory: storage that is wiped clean when power is cut from a device.

Ex. of nonvolatile memory = flash memory, hard disk, dvd storage. Flash memory: nonvolatile (permanent), chip-based storage, often used in mobile phones, cameras, and mp3 players. Slower than normal ram but holds its charge even when the power goes out.
