# Question: How Many Numbers Can Be Represented With 2 Bits?

## How many numbers can 16 bits represent?

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 many numbers are there in 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).

## Why is 25 cents called 2 bits?

Thus a bit is half of 25 cents. The origin of bit comes from the practice of cutting the Spanish dollar (peso) into eight radial pieces to make change. … Spanish dollars were deemed equivalent in value to a U.S. dollar. Thus, twenty-five cents was dubbed “two bits,” as it was a quarter of a Spanish dollar.

## Is a word two bytes?

One convention is that a byte is an 8-bit word, and a word is two bytes, and a double word (dword) is four bytes.

## What is the largest 4 bit number?

SixteenFigure 2.12 A four-bit binary number (called a nibble). Sixteen is the biggest decimal number we can represent in 4 bits.

## 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.

## How many numbers can be represented with 4 bits?

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 are 4 bits called?

nibbleIn 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.

## How much is 4 bits worth?

In early America, “bit” was used for some Spanish and Mexican coins that circulated and were worth one-eighth of a peso, or about 12 and one-half cents. So, in the U.S., two bits has routinely equaled about 25 cents, and four bits has typically been considered to be about 50 cents.

## How much is 25000 bits worth?

## How many bytes is a word?

2 bytesData structures containing such different sized words refer to them as WORD (16 bits/2 bytes), DWORD (32 bits/4 bytes) and QWORD (64 bits/8 bytes) respectively.

## Is a byte always 8 bits?

3 Answers. Yes, a byte is always 8 bits in modern computing. In the book, the word and the size of the word is explicitly mentioned, while there is not a word (haha) about bytes. … The whole size is expressed in (16 bit) words rather than bytes.

## What is slang for a \$20 bill?

\$10 bill is a “sawbuck”, a “ten-spot”, or a “Hamilton”. \$20 bill as a “Jackson”, or a “dub”, or a “double sawbuck”. Among horse-race gamblers, the \$50 bill is called a “frog” and is considered unlucky.

## 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.

## How many numbers can be represented with 3 bits?

## What is a group of 16 bits?

The term ‘word’ is used to describe the number of bits processed at a time by a program or operating system. So, in a 16-bit CPU, the word length is 16 bits. In a 32-bit CPU, the word length is 32 bits. … I used to ear them referred as byte, word and long word.

## Why do bytes have 8 bits?

The byte was originally the smallest number of bits that could hold a single character (I assume standard ASCII). We still use ASCII standard, so 8 bits per character is still relevant. This sentence, for instance, is 41 bytes. That’s easily countable and practical for our purposes.
