Data Processing

Data Processing is the process to convert data into useful information. For this purpose, different operations may be performed on data for getting result.Therefore, data processing is defined as:

“A sequence of operations on data to convert it into  information”

The important operation that can be performed on data are

  • Arithmetic and Logic Operation
  • Classification of data
  • Arranging of data into specific order

Data Processing Methods:

There are three methods for data processing

  1. Manual Processing of Data
  2. Mechanical Processing of Data
  3. Electronic Processing of Data


  1. Manual Processing of Data:

In this type of processing, data is processed manually without using any kind of machine or tool to get required results. In manual processing of data, all the calculations and logical operations are performed manually on the data, which is time taking and usually very slow. Similarly, data is transferred manually from one place to another manually not electronically. This method of processing of data is very slow, time consuming and errors may occur in the output.


  1. Mechanical Processing of Data:

In this type of processing, data is processed by using different devices like typewriters, mechanical printers or other mechanical devices. This method of data processing is fast and more accurate than manual processing of data.

  1. Electronic Processing of Data:

It is the modern technique to process data. In this type of  processing, the data is processed through computer. Data and the set of instructions are given to the computer as input and the computer automatically processed the data according to the given set of instructions, which is known as output or useful information. The computer is one of the well-known electronic processing of data machine. This method of processing of data is very fast, accurate and time saving. In this era, this types of processing is very common and growing rapidly.
