Document Summary

Functional parts: processor (cpu), primary memory (ram), secondary memory (a disk) & other components. The(cid:455)"(cid:396)e (cid:272)o(cid:374)(cid:374)e(cid:272)ted (cid:271)(cid:455) set of wires called a bus that transmits info b/t them. Basic organization: processor, storage for instructions/data, input/output devices. Called von neumann architecture: cpu provides arithmetic & control, ram & disk are memory storage, keyboard, mouse & display connect w/human operator. The central processing unit (cpu) (cpu) is brain of computer. It does arithmetic, moves data around & controls operation of everything else. Cpu has limited functions it can perform, but it performs them fast. Cpu uses internal clock to run basic operations. Mega is millions (106); giga is billion (109) It decides what to preform next based on previous inputs. It stores data that cpu is currently working on & instructions that tell cpu what to do w/data.
