01 Information Processing Cycle
- 1. The Information Processing Cycle Spiritwood High School
- 2. Introduction There are four stages to the information processing cycle: Input Process Output Distribute Spiritwood High School
- 3. Introduction These processes work together and repeat over and over: Spiritwood High School
- 4. The Four Stages Spiritwood High School
- 5. Stage 1: Input “You first have to get the data in” Our brain takes in information from our senses Computers need “peripherals” (extra components) to get information in ex/ keyboards, scanners, mice Spiritwood High School
- 6. Stage 2: Process Next, we need to ‘make sense of’ the data we have Our brain compares this to what we know and decides whether it is important enough to remember or not Computers use the CPU (the main chip inside) to make decisions, do calculations, and organize data ex/ Pentium-IV, Dual-Core Spiritwood High School
- 7. Stage 3: Output The next step is to get the results out from the process, and present them in a useable way Our brain makes our body respond by talking, moving, or writing Computers need “peripherals” to do this ex/ monitor, printer, data projector Spiritwood High School
- 8. Stage 4: Distribute Finally, the information needs to be sent elsewhere (or stored) so it can be used later Our brain makes “memories” of the information, and we may write it down to look over later Computers use “peripherals” to do this ex/ hard drive, CDs or DVDs to burn, Internet Spiritwood High School
- 9. …and back to Stage 1 Once the information is stored or distributed, it may be reviewed later by you or somebody else This takes us back to Stage 1 (Input), and the cycle starts again Spiritwood High School
- 10. A Real-World Example Spiritwood High School
- 11. The Example You are going to start a new job at an office (as a Secretary/ Receptionist). Your job includes typing letters and answering phones. How is the Information Processing Cycle involved? Spiritwood High School
- 12. Stage 1: Input “ You first have to get the data in” You see and feel the different papers you’re given to type When you go to work, you hear the phone calls, and answer them Spiritwood High School
- 13. Stage 2: Process Next, we need to ‘make sense of’ the data we have You decide to type the most important letters first You realize who is phoning, and decide to take a message Spiritwood High School
- 14. Stage 3: Output get the results out from the process, and present them in a useable way You print out the finished letter You write down the phone message Spiritwood High School
- 15. Stage 4: Distribute the information needs to be sent elsewhere (or stored) so it can be used later You save the letter as a computer file and mail it You also phone your boss and relay the message Spiritwood High School
- 16. …and back to Stage 1 You may need to find the file later, and update the letter The mailed letter is read by whoever you sent it to The phone message is heard by your boss Spiritwood High School
