Quick Answer: How many values can be represented by a single byte?

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 (28) 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 nbit 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 nth power minus 1. For example, the largest number we can represent in binary with n bits is 2n – 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 16bit 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. Hence, a processor with 16bit 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.
