As mentioned in the definitions of data processing above, it refers to the series of actions and operations. The following are the basic operations performed by computer for data processing.
1. Input-Output operations
2. Arithmetic and logic operations
3. Storing information
4. Retrieving information
5. Sorting data
6. Preparing data in a designed format
1. Input-output operations
This operation involves feeding data in some form which is understood by the computer and to obtain the output (i.e. result) in the format satisfying the needs of the users.
2. Arithmetic and logical operations
The computer can perform arithmetic operations (addition, subtraction, multiplication, division) as well as logic operations (checking conditions and comparing data to take the decision, performing OR, AND, and NOT operations).
3. Storing information
Another operation is storing of data in magnetic tapes, disks etc. The stored data or files occupy extremely less space as compared to the manually kept data or files in papers.
4. Retrieving information
The stored data can be fed to the computer system for processing. Repeated processing can be performed to obtain the desired results.
5. Sorting data
Sorting is the process of arranging data in specific order. It is a common practice in computers to arrange data in alphabetic, chronological (i.e. date wise) order.
6. Preparing data in a desired format
Computers are used to present the data in a meaningful or desired format.
