Document Summary

Hardware: the physical elements (printer, circuit board, wires, keyboard) Layers of computing system: each layer plays a specific role in the overall design of the system. Information within hardware within programming within operating systems within applications within communication: information: reflect way we represent information on a computer; managed using binary digits (1, 0. Abstraction: mental model, a way to think about something, removing or hiding complex details; leaves only information necessary to accomplish our goal. Miller"s law: human can actively manage about 7(-/+,2) pieces of information in short-term memory at once. Parallel computing: computers rely on interconnected central processing and/or memory units that increase processing speed. Networking: ethernet connected small computers to share resources.
