Q: Define the following terms Data, Data Processing, Information and Information System.

Answer:
Data:
A collation of raw facts and figures is called data. Data is collected from different ways. It is not useful and meaningful. It cannot be used for decision making. Data may be in the form of numbers. characters. (symbols. sounds, images and video clips etc. For example, when a student gets admission in a college he fills an admission form. The form contains raw facts and figures about the student. These facts and figures are student's name. father name. address, phone. marks etc.
Data Processing:
The process of converting data into useful information is called data processing. For this purpose, we perform different operations on data. The most common operations performed on data are:
•           Arithmetic operations Logical operations
•           Arranging data in a specific order
•           Classification of data
•           Searching of data
Information:
The processed data is called information. Information is useful and meaning. It can be used for decision-making. Data is used as input for data processing. Information is output of data processing. For example, if we arrange the student’s admission forms in descending order with respect to marks. we easily make a list of the students who got admission in college on limited seats.
Information System:
The system that takes data as input. process it and produce useful information as output is called information system. An information system consists of computer hardware, software. data. procedures and users. We provide data for system and system provides information. The programs used f processing are very important part of information system.
