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:

1. Data input
2. Data process
3. Data storage
4. 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.
