01 Information Processing Cycle

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