## How many values can be held in a byte?

A **byte** is a group of **8 bits**. A bit is the most basic unit and **can** be either 1 or 0. A **byte** is not just 8 **values** between 0 and 1, but 256 (2^{8}) different combinations (rather permutations) ranging from 00000000 via e.g. 01010101 to 11111111. Thus, one **byte can** represent a decimal number between 0(00) and 255.

## How many different values can n 1 bits represent?

Computer uses a fixed number of **bits** to **represent** a piece of data, which **could** be a number, a character, or others. A **n**–**bit** storage location **can represent** up to 2^**n distinct** entities. For example, a 3-**bit** memory location **can** hold **one** of these eight binary patterns: 000, 001, 010, 011, 100, 101, 110, or 111.

## How many bits are there in a single byte?

A **byte** is a grouping of eight **bits**. **Byte**-addressable means that the computer stores data in **bytes** instead of **single bits** for example.

## How many values can a bit represent?

While a single bit, on its own, is able to represent only **two values**, a string of bits may be used to represent larger values. For example, a string of three bits can represent up to **eight** distinct values as illustrated in Table 1.

## What is the highest value in one byte?

The **maximum** decimal **number** that can be represented with 1 **byte** is 255 or 11111111.

## How many numbers can you represent with 2 bytes?

1 **byte would be 2** decimal **digits** and **you could represent** values between 0 up to 100 (not included). **2 bytes would be** 4 decimal **digits** and **you could represent** values between 0 up to 10000 (not included).

## How many different values can 4 bits represent?

The most common is hexadecimal. In hexadecimal notation, **4 bits** (a nibble) are **represented** by a single digit. There is obviously a problem with this since **4 bits** gives 16 possible combinations, and there are only 10 **unique** decimal digits, 0 to 9.

## What is the biggest number N bits can represent?

The largest **number** we **can represent** (since we need 0) is the base to the **n**^{th} power minus 1. For example, the largest **number** we **can represent** in binary with **n bits** is 2** ^{n}** – 1.

## What’s the largest value you can represent in binary with just 3 bits?

The largest decimal number that we can represent with 3 bits is 7, if **binary number system** is unsigned that means you can’t represent any negative number in this system. Because all three bits are used in this system. The binary number is 111, which is equal to 7 in decimal.

## What is the smallest unit of memory?

**Byte**, the basic unit of information in computer storage and processing. A **byte** consists of 8 adjacent binary digits (bits), each of which consists of a 0 or 1. The string of bits making up a **byte** is processed as a unit by a computer; **bytes** are the smallest operable units of storage in computer technology.

## Why do we use bytes?

A **byte** is the unit most computers **use** to represent a character such as a letter, number or typographic symbol. Each **byte** can hold a string of bits that **need** to be **used** in a larger unit for application purposes. As an example, a stream of bits can constitute a visual image for a program that displays images.

## How many bytes is a word?

A byte is eight bits, a word is **2 bytes** (16 bits), a doubleword is **4 bytes** (32 bits), and a quadword is **8 bytes** (**64** bits). Figure 29-2 shows the byte order of each of the fundamental data types when referenced as operands in memory.

## How many unique values can a 16 bit immediate value hold?

A **16**–**bit** integer **can** store 2** ^{16}** (or 65,536)

**distinct values**. In an unsigned representation, these

**values**are the integers between 0 and 65,535; using two’s complement, possible

**values**range from −32,768 to 32,767. Hence, a processor with

**16**–

**bit**memory addresses

**can**directly access 64 KB of byte-addressable memory.

## Which values can be stored in a single bit?

Because a single bit can only store two values, bits are combined together into large units in order to hold a greater **range** of values. A nibble is a group of FOUR bits. This gives a maximum number of 16 possible different values.

## What is bit short for?

A **bit** (**short for** “binary digit”) is the smallest unit of measurement used to quantify computer data. It contains a single binary value of 0 or 1. While a single **bit** can define a boolean value of True (1) or False (0), an individual **bit** has little other use.
