Document Summary

A computer is a data processing device that performs 4 major functions: Data a representation of a fact, figure, or idea (number, word, picture, etc. ) Information data that has been organized or presented in a meaningful/useful fashion. Input data -> process data into information -> output information. Hardware any part of the computer that you can physically touch. Operating system program that controls how your computer system functions. Hardware + software work together to process data into info. Input devices: allow you to enter data + instructions to your computer. Output devices: lets you send processed data out of your computer in the form of text, pictures, sound, or video. Processing: motherboard the main circuit board that contains the central electronic (cid:272)o(cid:373)po(cid:374)e(cid:374)ts of the (cid:272)o(cid:373)pute(cid:396), i(cid:374)(cid:272)ludi(cid:374)g the (cid:272)o(cid:373)pute(cid:396)"s p(cid:396)o(cid:272)esso(cid:396) (cpu), its memory, and the many circuit boards that help the computer function.
