Homework - Steps for information processing

Pg 13 in your textbook.
There are nine steps of information processing. Name the nine steps and consider the following example. Write up the example under the nine steps.

Students decide to collect money each week for social service. They use a spreadsheet to monitor the collection. Jenny acquires data each week by recording on paper the amount raised and the date. She then inpts this data into the spreadsheet using the keyboard. The data is validated by inbuilt formulas that check the amount is reasonable. The data for each week is manipulated using a formula to total the amounts. The file is saved to the hard drive after processing. On the next collection day, the file is retrieved and new data added. Output in the form of a printout is obtained at the end of each month. Copies are printed, communicating the information to all students by hand. At the end of they ear, when the file is no longer needed, Jenny deletes the file from her computer.
