Document Summary

Computing system: computer hardware, software, and data, which interact to solve problems. Computer hardware: the collection of physical elements that make up the machine and its related pieces: boxes, circuit boards, chips, wires, disk drives, keyboards, monitors, printers, and so on. Computer software: the collection of programs that provide the instructions that a computer carries out. Information (innermost layer)- reflects the way we represent info. on a computer; info. on a computer is managed using binary digits, 1 and 0; types of info. we manage: numbers, text, images, audio, video. Hardware (next layer)- consists of the physical hardware of a computer system; includes devices such as gates and circuits, which control the flow of electricity in fundamental ways; central processing unit (cpu), memory. Programming (next layer)- deals with software, the instructions used to accomplish computations and manage data; programs take many forms, performed at many levels, implemented in many languages; goal is to solve problems.
