Dear Viewer! as you have learnt that computer is such a machine which solves our problems. Its basic function is to receive data (input), process it and give us the information (out put) Here you will learn about what is Data Processing? But first you should know about the data.
Data:
Anything in raw form like numbers, words and facts are called data.
Types of data:
There are three types of data.
Alphabetic data includes all the alphabetic letters either capital or small, For example
A B C D E F G H I
a b c d e f g h i
2. Numeric data:
Numeric data includes decimal number from 0-9 and decimal point notations. For example
1 2 3 4 5 6 7 8 9
55 2.8 15.8 6.8
3. Alphanumeric data:
Alphanumeric data include alphabetic, number and special character/Symbols. For example
Aa Bb Cc Dd Ee
1 2 3 4 5 6 7 8 9 10 1.2 5.8 3.3
! @ # (* & $ - +) [$ V} =
Information: Meaningful form of data is called information. For Example
Ali goes to Lahore.
I read in class five.
In the evening, we go to play ground.
1. Input:
When data is taken from somewhere to perform any specific operation on it is known as "input”.
For example your teacher writes 4, 9 on the White Board. Can you tell what is 4 and 9?
Yes viewers it is Data.
2. Process:
Now you have data on your copy and you are going to do sum. The calculation that you
Will make in your mind or in your copy is called Process. Dear Kids! Taking sum or doing
Mathematical operations are the only way to process the data.
You can process the Data from the many other ways too.
3. Output :
The result which you get on monitor after processing is called output.
Electronic data Processing:
When the data is entered, processed and outputted by the computer then it is known as Electronic Data Processing.
