Document Summary

Computing systems -dynamic entitiesused to solve problems and interact with their environment. Hardware - the physical elements of a computing system (printer, circuit boards, wires, keyboard ). Software - the programs that provide the instructions for a computer to execute. Data - information in a form a computer can use. Information reflects the way we represent information on a computer information on computers is managed using binary digits numbers, text, images, audio and video are all represented using binary format. Hardware physical hardware of a computer system includes devices such as gates and circuits, which control the flow of electricity this circuitry gives rise to components such as the cpu and memory. Programming software instructions used to accomplish computations and manage data the goal is to solve problems. Operating system help us interact with the computer system and manage the way hardware devices, programs and data interact ex.
