Document Summary

Computing system: used to solve problems and interact with its environment. Composed of hardware + software, and the data that they manage. Computer hardware: physical elements that make up the machine (ex. Boxes, circuit boards, chips, printer, monitor, wires, disk drives) Computer software: programs that provides instructions that a computer carries out. Figure 1. 1: the layers of a computing system. Information the way we represent info on a computer- purely conceptual level binary digits are used (1, 0) Hardware physical hardware of a computer system includes gates and circuits (control the flow of electricity) core electronic circuitry gives rise to specialized hardware components (ex. Programming deal with software- instructions used to accomplish computations and manage data programs can be performed in many languages, levels and take many forms goal: to solve problems. Operating systems (os) every comp has an os, helps manage comps resources. Os interact with computer systems and manage how hardware devices, programs, and data interact.
