What is the Difference between Data and Information ?

Data and information are similar concepts, but they are not the same thing. The main difference between data and information is that data are a part and information is the whole. Explore how data and information differ through definitions and examples. The word data can be used for a singular fact or a collection of facts. The word datum is still the technically correct singular form of data, but is rarely used in common language.

Data are units of information , often numeric, that are collected through observation. Although the terms "data" and "information" are often used interchangeably, these terms have distinct meanings. In some popular publications, data are sometimes said to be transformed into information when they are viewed in context or in post-analysis. Data are used in scientific research , businesses management e. Data are measured , collected and reported , and analyzed , and from data visualations such as graphs, tables or images are produced.

There is a subtle difference between data and information. Data are the facts or details from which information is derived. Individual pieces of data are rarely useful alone. For data to become information, data needs to be put into context. Data are simply facts or figures — bits of information, but not information itself. When data are processed, interpreted, organized, structured or presented so as to make them meaningful or useful, they are called information. Information provides context for data.


The concepts of ”data”, “information”, “meaning” and “learning” are vitally important in a Computer technologies are now essential in modern libraries and are.


Difference between Information and Data

Research process starts with the collection of data, which plays a significant role in the statistical analysis. However, in general, it indicates the facts or statistics gathered by the researcher for analysis in their original form. While data is an unsystematic fact or detail about something, information is a systematic and filtered form of data, which is useful. In this articl, you can find all the important differences between data and information.

Difference Between Data and Information

Difference Between Data and Information Explained

Computer data is information processed or stored by a computer. This information may be in the form of text documents, images, audio clips, software programs, or other types of data. Computer data may be processed by the computer's CPU and is stored in files and folders on the computer's hard disk. At its most rudimentary level, computer data is a bunch of ones and zeros, known as binary data.

A data processing system is a combination of machines , people, and processes that for a set of inputs produces a defined set of outputs. The inputs and outputs are interpreted as data , facts , information etc. A term commonly used synonymously with data or storage codes processing system is information system. The first machines used for data processing were punched card machines , now computers are used.

Data is a raw and unorganized fact that required to be processed to make it meaningful. Data can be simple at the same time unorganized unless it is organized. Generally, data comprises facts, observations, perceptions numbers, characters, symbols, image, etc. Data is always interpreted, by a human or machine, to derive meaning. So, data is meaningless. Data contains numbers, statements, and characters in a raw form. What is Information?

Key Differences Between Data and Information

Data procesing refers to the transformating raw data into meaningful output. Data Input - the collected data is converted into machine-readable form by an input device, and send into the machine. Processing is the transformation of the input data to a more meaningful form information in the CPU. Output is the production of the required information, which may be input in future. Data capture is the process of obtaining data in a computer-sensible form for at the point of origin the source document itself is prepared in a machine-sensible form for input.

The words Data and Information may look similar and many people use these words very frequently, But both have lots of differences between them. It is not enough to have data such as statistics on the economy. Data themselves are fairly useless, but when these data are interpreted and processed to determine its true meaning, they becomes useful and can be named as Information. Information is data that has been processed in such a way as to be meaningful to the person who receives it. Data is the term, that may be new to beginners, but it is very interesting and simple to understand. It can be anything like name of a person or a place or a number etc.
