## How are images represented in a computer?

Data in **computers** is stored and transmitted as a series of ones and zeros (also known as Binary). To store an **image** on a **computer**, the **image** is broken down into tiny elements called pixels. In order for the **computer** to store the **image**, each pixel is **represented** by a binary value.

## How can computers represent text as numbers?

All types of data are stored inside the **computer** as **numbers**. Each character in **text** is stored as **a number** that **represents** the character. In personal **computers**, a common way to **do** this is to use ASCII – the American Standard Code for Information Interchange.

## How do computers represent real numbers in memory?

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**. The bits allocated for a floating point **number** are divided up into a sign bit, a certain **number** of bits for an exponent, and a certain **number** of bits for a mantissa.

## How are numbers represented in a modern computer?

**Computers represent** data in sets of binary **digits**. The **representation** is composed of bits, which in turn are grouped into larger sets such as bytes. Table 2: Number of values for a bit string. A bit is a binary digit that **represents** one of two states.

## How is sound represented on a computer?

**Sound** travels in waves. Since **computers represent** data in digital form, (as bits and bytes) the **sound** in analog form must be converted to digital form to be retained. Likewise then the digital **representation** of the **sound** must then be converted to analog form for our ears to hear it.

## How audio is stored in computer?

Sounds created on a **computer** exist as digital information encoded as **audio** files. Digital **sound** is broken down into thousands of samples per second. Each **sound** sample is **stored** as binary data.

## 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 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 do you represent a character on a computer?

**Representation of characters**

**Computers**work in binary.- ASCII uses seven bits, giving a
**character**set of 128**characters**. - ‘A’ is
**represented**by the denary number 65 (binary 1000001,hexadecimal 41), ‘B’ by 66 (binary 1000010, hexadecimal 42) and so on up to ‘Z’, which is**represented**by the denary number 90 (binary 1011010, hexadecimal 5A).

## Why can’t computers represent every possible number in mathematics?

Although there are infinitely many integers, in most programs the result of integer computations can be stored in 32 bits. In contrast, given any fixed **number** of bits, most calculations with real **numbers** will produce quantities that cannot be exactly **represented** using that many bits.

## How do computers store numbers?

**Numbers are** stored on the **computer** in binary form. In other words, information is encoded as a sequence of 1’s and 0’s. On most **computers**, the memory is organized into 8-bit bytes. The ½ decimal digit means twice the **number** of alternatives or one additional binary bit.

## What is the most common integer representation in computers?

The most common representation of a positive integer is a string of bits, using the **binary** numeral system. The order of the memory bytes storing the bits varies; see endianness. The width or precision of an integral type is the number of bits in its representation.

## How do computers compare numbers?

The CPU uses a digital comparator: A digital comparator or magnitude comparator is a hardware electronic device that takes two **numbers** as input in binary form and determines whether one **number** is greater than or less than or equal to the other **number**.

## What’s the largest decimal number that you can represent with 3 bits?

Answer and Explanation:

The **largest decimal number that you can represent with 3 bits** is 7. A **3**–**bit number** consists of **3** binary **digits**, (that is, combination of **three** binary

## How do computers 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. The circuits in a **computer’s** processor are made up of billions of transistors.
