Which of the following best describes how computing devices represent information? D. A computer represents information as bits which contain 8 bytes. … Your computer uses 4 bits to represent decimal numbers (0 1 2 3 and so on) in binary.

## How does a computer device represent information?

Computers use binary – the digits 0 and 1 – to store data. … It is represented by a 0 or a 1. Binary numbers are made up of binary digits (bits) eg the binary number 1001.

## What is the best explanation for why digital data is represented in binary?

What is the best explanation for why digital data is represented in computers in binary? It’s easier cheaper and more reliable to build machines and devices that only have to distinguish between binary states.

## How do we represent information?

“Representation Information: The information that maps a Data Object into more meaningful concepts. An example is the ASCII definition that describes how a sequence of bits (i.e. a Data Object) is mapped into a symbol.” … The summary is that “Data interpreted using its Representation Information yields Information”.

## Does abstraction represent complex information?

An abstraction is a simplified representation of something more complex. Abstractions allow you to hide details to help you manage complexity focus on relevant concepts and reason about problems at a higher level. Modern life is filled with complex systems.

## Which is true about how computers represent numbers?

Computers are designed to use binary digits to represent numbers and other information. The computer memory is organized into strings of bits called words of same length. Decimal numbers are first converted into their binary equivalents and then are represented in either integer or floating point form.

## Which of the following best describes computer data processing?

Data processing is simply the conversion of raw data to meaningful information through a process. … Similar to a production process it follows a cycle where inputs (raw data) are fed to a process (computer systems software etc.) to produce output (information and insights).

## Which of the following is defined as a collection of computers and devices connected together via communication link?

network

A network is a collection of computers and devices connected together via communications devices and transmission media.

## How are characters represented in a computer?

Computers work in binary . As a result all characters whether they are letters punctuation or digits are stored as binary numbers. All of the characters that a computer can use are called a character set .

## What is computer 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.

## How does the computer interpret data and information?

In a computer the processor is the center of activity. … The central processing unit consists of electronic circuits that interpret and execute program instructions as well as communicate with the input output and storage devices. It is the central processing unit that actually transforms data into information.

## Can all digital data be represented in binary?

At one of the lowest levels of abstraction all digital data can be represented in binary using only combinations of the digits zero and one. Binary can be used to represent more complex higher level abstractions including but not limited to numbers characters and colors.

## Why is digital data represented in computers using the binary number system?

Computers don’t understand words or numbers the way humans do. … To make sense of complicated data your computer has to encode it in binary. Binary is a base 2 number system. Base 2 means there are only two digits—1 and 0—which correspond to the on and off states your computer can understand.

## Why is data represented as binary in computer systems?

Computer systems are designed to process data. In order to do so computers use electronic circuits that function as switches that can be turned on or off. We use a binary form to represent these two states: A 0 represents when a switch is off.

## What are the two types of information representation?

Representation of Data/Information
• Binary number system consists of only two values either 0 or 1.
• Octal number system represents values in 8 digits.
• Decimal number system represents values in 10 digits.
• Hexadecimal number system represents values in 16 digits.

## How do you represent information visually?

How to present data visually (data visualization best practices)
1. Avoid distorting the data. …
2. Avoid cluttering up your design with “chartjunk” …
3. Tell a story with your data. …
4. Combine different types of data visualizations. …
5. Use icons to emphasize important points. …
6. Use bold fonts to make text information engaging.

## What are the different ways to present information?

Ideas for presenting content
1. Take a multisensory approach – use real experiences physical activity and manipulables.
2. Provide multiple visual and concrete examples of information. …
3. Support text with visuals and audio. …
4. Present digital rather than printed text so that students can personalise the ways they access it.

## How does abstraction help represent complex information?

An abstraction is a simplified representation of something more complex. Abstractions allow you to hide details to help you manage complexity focus on relevant concepts and reason about problems at a higher level. Modern life is filled with complex systems. Think for example about a train system.

## What is managing complexity in computer science?

In computer science abstraction is a technique for managing complexity of computer systems. It works by establishing a level of complexity on which a person interacts with the system suppressing the more complex details below the current level.

## What is algorithm abstraction?

Abstraction is the process of filtering out – essentially ignoring – the characteristics of problems that are not needed in order to concentrate on those that are needed. It is also the filtering out of specific details. … Abstraction allows programmers to create a general idea of what the problem is and how to solve it.

## How does computer store represent real numbers?

On a computer a real number is often called a floating point number. Floating point numbers are stored in a fixed number of bits of computer memory.

## What are the methods of representing characters in computer memory?

• Binary Coded Decimal (BCD)
• American Standard Code for Information Interchange (ASCII)
• Extended Binary Coded Decimal Interchange Code (EBCDIC)
• Indian Standard Code for Information Interchange (ISCII)
• Unicode.

## How do computers represent floating point numbers?

Eight digits are used to represent a floating point number : two for the exponent and six for the mantissa. The sign of the mantissa will be represented as + or – but in the computer it is represented by a bit: 1 means negative 0 means positive. This representation makes it easy to compare numbers.
