After collecting data, it is processed to convert into information. The data is processed again and again until accurate result is achieved. This is called data processing cycle . Data processing cycle involves following three basic activities: Major Activities Involved in Data Processing Cycle Explain Data processing cycle 1. Input 2. Processing 3. Output 1. INPUT It is the process in which collected data is given to computer after converting into binary form. Input step can be further divided into following steps: i) Planning Here objectives of data processing are defined. For example, in examination system, objective is to process student examination data to get result cards. ii) Data Collecting Here data is collected. Data is the raw material for data processing. This must be accurate for getting accurate results. iii) Input Here data is entered into computer. iv) Verification Here collected data is verified to determine whether it is valid for ...
