1.6.1 Data Processing – CCC – Course on Computer Concepts

Concept of Data Processing

Data processing is the process in which the information is gathered/collected and stored in the form of electronic media and manipulated into a more useful form.

Data Processing Cycle

The Data Processing Cycle consists of the following steps:

. Input

. Processing

. Output

. Storage

Storage: Store and Retrieve

Input: Sorting, calculating, summarizing, comparing

Data: Collection, Conversion

Output: Communicate and Reproduce

In this step the input data are coded or converted into machine readable form, so that it can be proceed through a computer.

Functions of Data Processing

The Four major functions of Data Processing of a computer are:

  1. Validating
  2. Sorting
  3. Analyzing
  4. Reporting

Validation: Validating of data helps user to identify invalid cases, variables and data value in the particular data. After Validation data will be clean, correct and useful.

Sorting: Arranging data in specific order is called sorting. Sorting- Alphabetical order. For example- Names in telephone book are sorted in alphabetical order.

Analyzing: It is the process in which data is organized, reviewed, verified and interpreted.

Reporting: In this function a collection of data is condensed and certain conclutsions from the data are represented in a simple form.
