The Data Processing Cycle of Computer
- The computer Data Processing is any process that a computer program does to enter data & summarise, analyse or convert data into useable information.
- The process may be automated & run on a computer.
- It involves recording, analysing, storing, summarising & storing data.
- Because data are most useful when it is well presented & informative.
The Data Processing Cycle:
- Data Processing cycle described all activities which are common to all data processing systems from manual to electronic systems.
- These activities can be grouped in four functional categories, viz., data input, data processing, data output and storage, constituting what is known as a data processing cycle.
- The main aim of data processing cycle is to convert the data into meaningful information.
- Data processing system are often referred to as Information System.
- The Information System typically take raw Data as Input to produce Informationas Output.
The data processing cycle contains main four functions:
- Data input
- Data process
- Data storage
- Data output
1. DATA INPUT-
- The term input refers to the activities required to record data.
- It’s a process to entered data in to computer system.
- So before we input any data, it is necessary to check or verify the data context.
2 . DATA PROCESSING –
- The term processing includes the activities like classifying, storing, calculating, comparing or summarising the data.
- The processing means to use techniques to convert the data into meaningful information.
3. DATA OUTPUT –
- It’s a communication function which transmits the information to the outside world.
- After completed the process the data are converted into the meaningful ino Sometimes the output also includes
- the decoding activity which converts the electronically generated information into human readable form.
4. DATA STORAGE –
- It involves the filling of data & information for future use.
