What is Data and Information ?
Ans-Data and Information are related but distinct concepts in the context of information systems, computing, and general communication:
Data:
Definition: Data are raw, unprocessed facts and figures without any context. It can be numbers, characters, images, or other outputs from devices that sense the world.
Characteristics:
Unorganized: Data is often unstructured and unprocessed.
Raw: It is the raw material from which information is derived.
Types: Can be qualitative (descriptive) or quantitative (numerical).
Examples: A list of temperatures, customer names, or transaction amounts.
Information:
Definition: Information is data that has been processed, organized, or structured in a way that makes it meaningful and useful.
Characteristics:
Processed: Information is derived from data through processes like analysis, interpretation, or organization.
Meaningful: It provides context and relevance, which can be used for decision-making.
Structured: Information is often structured to communicate a message or support analysis.
Examples: A report showing the average temperature over a week, a customer purchase history summary, or a financial statement.
Key Differences:
Nature:
Data is raw and unorganized.
Information is processed and organized.
Usage:
Data alone does not have meaning; it is used as input for processing.
Information is the output of data processing and has meaning for decision-making.
Value:
Data has potential value when processed.
Information has actual value as it aids in decision-making or understanding
