What is the difference between the storage and output phases of the IPOS cycle? Storage is when the raw data is saved without being processed first. It can be recalled for use at a later time. Output is what happens after the data is processed into information. Storage is when the computer displays the information so that the user can write it down for safekeeping and future use. Output is when the computer provides an actual file for storage so that the user does not have to take further action. Output is when the computer displays the results of the processing stage so that the user can understand them. Storage is when those results are saved for future access. Storage and output are usually the same action. Only in rare instances are they different.
