1)- Capturing data :-Collecting the required data using source ,documents or preformat 

2)-Input Of data :- Feeding data to the computer for processing is known as input 

3)-.Storage of data :- The data at the time of input process and the information (output)  obtained as a result of processing is also stored in the computer. 

4)-Processing :-manipulating data Process is the various operations like calculation, classification, comparison, sorting, filtering, summarising etc. which are carried out.
