 # Question: How Many Numbers Can 16 Bits Represent?

## How many numbers can be represented with 2 bits?

A 2-bit system uses combinations of numbers up to two place values (11).

There are four options: 00, 01, 10 and 11.

A 1-bit image can have 2 colours, a 4-bit image can have 16, an 8-bit image can have 256, and a 16-bit image can have 65,536..

## What is the maximum value for a 16 bit number?

A 16-bit integer can store 216 (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.

## How do you add 16 bit numbers?

Algorithm –Load both the lower and the higher bits of first number at once.Copy the first number to another register pair.Load both the lower and the higher bits of second number at once.Add both the register pairs and store the result in a memory location.

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

0The smallest number which can be represented by 3 bits is 0 in decimal and 000 in binary. The largest number which can be represented by 3 bits is 7 in decimal and 111 in binary.

## How many numbers can 64 bits represent?

As a recap, remember that the maximum number stored in a 64 bit register / variable is 2^64 – 1 = 18446744073709551615 (a 20 digit number).

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

7Explanation: 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.

## How many numbers can 4 bits represent?

16In 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 a 16 bit number?

In computer architecture, 16-bit integers, memory addresses, or other data units are those that are 16 bits (2 octets or 2 Bytes) wide. … If we consider the signed range of integer values that can be stored in 16 bits is −32,768 (−1 × 215) through 32,767 (215 − 1).

## How many numbers can be represented with 10 bits?

## What are 4 bits called?

In computing, a nibble (occasionally nybble or nyble to match the spelling of byte) is a four-bit aggregation, or half an octet. It is also known as half-byte or tetrade. In a networking or telecommunication context, the nibble is often called a semi-octet, quadbit, or quartet.

## What is the name for 4 bits and for 16 bits?

BytesCommon binary number lengths From there, a group of 4 bits is called a nibble, and 8-bits makes a byte. Bytes are a pretty common buzzword when working in binary. Processors are all built to work with a set length of bits, which is usually this length is a multiple of a byte: 8, 16, 32, 64, etc.

## What is a group of 16 bits called?

hextetIn computing, a hextet is a sixteen-bit aggregation, or four nibbles. As a nibble typically is notated in hexadecimal format, a hextet consists of 4 hexadecimal digits. A hextet is the unofficial name for each of the 8 blocks in an IPv6 address.
