## How does a computer 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.

## How can computers represent pictures as numbers how can computers represent text as numbers?

Computers represent pictures as numbers as follows:

Each pixel is defined by numbers expressed in bits. The digits of the binary number system are 0 and 1. Each binary number is called a “bit”.

## How text based data is represented?

All computer data including text, images and sound is represented using binary. Work between ASCII and Unicode to understand the relationship between them. Encode images using binary.

## How do digital systems represent text?

In Digital Technologies, discrete representation of information using number codes. Data may include characters (for example, alphabetic letters, numbers and symbols), images, sounds and/or instructions that, when represented by number codes, can be manipulated, stored and communicated by digital systems.

## Which of the following are numbers to a computer?

Table of the Numbers Systems with Base, Used Digits, Representation, C language representation:

Number system Base Used digits
Binary 2 0,1
Octal 8 0,1,2,3,4,5,6,7
Decimal 10 0,1,2,3,4,5,6,7,8,9

## Why do computer use 1s and 0s?

Computers use binary – the digits and 1 – to store data. The circuits in a computer’s processor are made up of billions of transistors. A transistor is a tiny switch that is activated by the electronic signals it receives. The digits 1 and 0 used in binary reflect the on and off states of a transistor.

## How do computers represent sounds?

Sound needs to be converted into binary for computers to be able to process it. To do this, sound is captured – usually by a microphone – and then converted into a digital signal. The samples can then be converted to binary.

## Which data are mainly numbers?

Explanation:

• the correct answer is QUANTITATIVE since it refers to the information that is collected as, or can be translated into, numbers, which can then be displayed and analyzed mathematically.
• thanks.
• ty.

## What is the letter A in binary?

ASCII – Binary Character Table

Letter ASCII Code Binary
A 065 01000001
B 066 01000010
C 067 01000011
D 068 01000100

## How data is represented?

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. The circuits in a computer’s processor are made up of billions of transistors.

## Which is type of coding system?

There are four types of coding: Data compression (or source coding) Error control (or channel coding) Cryptographic coding.

## How do computers convert data into information?

The processor, more formally known as the central processing unit (CPU), has the electronic circuitry that manipulates input data into the information people want. The central processing unit executes computer instructions that are specified in the program.

## What is digital data and its types?

Digital data can be classified into three forms: – Unstructured. – Semi-structured. – Structured. •

## How do computers represent complex information?

Computing devices use patterns of bits to represent complex information. Depending on context the same sequence of bits may represent different types of information. D. Common abstractions that are represented by computing devices include numbers, characters, and color.

## How is data represented in the electronic memory?

Computers Are Electronic Machines. The computer uses electricity, not mechanical parts, for its data processing and storage. To process real-world data in the computer, we need a way to represent the data in switches. Computers do this representation using a binary coding system.
