The document discusses the basic components and functions of a computing system. It defines key concepts like data, information, and system. It also outlines the typical resources that make up an information system, including human resources, hardware resources, software resources, and data resources. Finally, it provides examples of input devices, central processing units, storage devices, and output devices that are common parts of a computer system.
2. Data (DATA): As a result that it was observed the fact that occurred Information (Information): Data + meaning The data which have a meaning for a particular person The information varies among people With the communication Action to communalize the meaning of the information A consignor, a guard, a medium (the media), protocol (rule)
3. Resources of the information system (computing system) ・ Human resources: A user, an analyst, a programmer, operator hardware resources: A machine, storage medium, network software resources: A program, a procedure, data resources System (system): Factor to act with a common purpose Function of the system Input, processing, output, feedback, control (self-monitoring function, self-control function)
6. ① Input deviceThe device which casts data into a computer(example) A keyboard, a mouse, bar code leader ② Central processing unit (CPU)Brain of a computer comprised of an arithmetic unit and a control unit(example) The processor series ,POWER PC series of x86 origin The SPARC series
9. ④ Output device The device which provides handled information to a user (user)(example) A printer, display ③ Storage deviceMain memory and auxiliary memory. I memorize data and an order(example) SDRAM, hard disk
