Data representation in computer science is about how a computer interprets and functions with different types of information.
Different information types require different representation techniques.
For instance, a video will be represented differently than a text document..

Data representation, a fundamental concept in computing, refers to the various ways that information can be expressed digitally.
The interpretation of this data plays a critical role in decision-making procedures in businesses and scientific research..

What is data representation in computer fundamentals?
Data representation is how data is represented and presented to users.
For example, human languages represent the physical world (written form) and the digital world (spoken or written form).
Data representations include charts, graphs, tables, and other tools for representing quantitative data..

What is the basic concept of data representation?
• Data Representation refers to the form in which data is stored, processed, and transmitted. • Devices such as smartphones, iPods, and computers store data in digital formats that can be handled by electronic circuitry..
What is the basic data representation?
Data representation can be referred to as the form in which we stored the data, processed it and transmitted it.
In order to store the data in digital format, we can use any device like computers, smartphones, and iPads.
Electronic circuitry is used to handle the stored data..

What is the data representation method?
ASCII stands for American Standard Code for Information Interchange.
ASCII code allows computers to understand how to represent text.
In ASCII, each character (letter, number, symbol or control character) is represented by a binary value..
What is the main purpose of data representation?
Data representations are useful for interpreting data and identifying trends and relationships.
When working with data representations, pay close attention to both the data values and the key words in the question.
When matching data to a representation, check that the values are graphed accurately for all categories..
Where is data representation used?
Data Representation refers to the form in which data is stored, processed, and transmitted.
Devices such as smartphones, iPods, and computers store data in digital formats that can be handled by electronic circuitry..
Why do we study data representation?
Data representation is about understanding how each type of data is processed, stored and displayed within a device, and what impacts this has on how types of data are used.
It contributes to our understanding of what computers are able to do and what they can't do .

Let's discuss it one by one.
Numbers – Numbers are not represented as ASCII but by bit patterns. Text – Text is also represented as bit pattern or sequence of bits(such as 0001111). Audio – Audio signal is a representation of sound or music. Video – Images –Types of data representation

It contributes to our understanding of what computers are able to do and what they can't do - Data representation is how data is represented and presented to users.
For example, human languages represent the physical world (written form) and the digital world (spoken or written form).
Data representations include charts, graphs, tables, and other tools for representing quantitative data. - Stacked bar chart is the best method of data representation when data is of differing nominal values and needs to represent quantitative data on different axes.
A stacked bar chart is a visual representation of data that displays multiple variables for each category. - The transformation of data through visual methods like graphs, diagrams, maps and charts is called representation of data.
Such a form of the presentation of data makes it easy to understand the patterns of population growth, distribution and the density, sex ratio, age–sex composition, occupational structure, etc.

Way in which data is arranged and accessed in computer memory
Data structure alignment is the way data is arranged and accessed in computer memory.
It consists of three separate but related issues: data alignment, data structure padding, and packing.
Data structure or code used internally by a compiler or virtual machine to represent source code
An intermediate representation (IR) is the data structure or code used internally by a compiler or virtual machine to represent source code.
An IR is designed to be conducive to further processing, such as optimization and translation.
A good IR must be accurate – capable of representing the source code without loss of information – and independent of any particular source or target language.
An IR may take one of several forms: an in-memory data structure, or a special tuple- or stack-based code readable by the program.
In the latter case it is also called an intermediate language.
In computing, a data type whose structure is not defined in an interface
In computer science, an opaque data type is a data type whose concrete data structure is not defined in an interface.
This enforces information hiding, since its values can only be manipulated by calling subroutines that have access to the missing information.
The concrete representation of the type is hidden from its users, and the visible implementation is incomplete.
A data type whose representation is visible is called transparent.
Opaque data types are frequently used to implement abstract data types.
