A bit is typically the smallest unit of memory in an electronic device. As it is based on a binary system, it can contain only one of two possible values: 1 or 0, which generally relate to that electronic memory element being set On or Off, respectively.

A byte consists of 8 bits and is typically used to represent a single logical character. As each of the 8 bits can contain either of two binary values (1 or 0) the total number of combinations in any byte is therefore 2*2*2*2*2*2*2*2 = 2**8 = 256.

The literal character for any particular byte value can vary depending on the Code being used by the computer. For example, a byte with a current value of 90 is generally "Z" in ASCII but is "!" in EBCDIC. But even within the general structure of ASCII there can be special character sets employed wherein some or all of the values are agreed to represent other characters used in foreign languages or in special applications.


  • 1 bit (b) = 1 binary value (0 or 1)
  • 1 byte (B) = 8 bits = one logical character
  • 1 kilobyte (KB) = 1024B
  • 1 megabyte (MB) = 1024KB
  • 1 gigabyte (GB) = 1024MB
  • 1 terabyte (TB) = 1024GB

How many bits in 9 bytes?

As a byte is typically a sequence of 8 bits, there are a total of 72 bits in nine bytes.

How many bits a byte?

Generally speaking, eight bits to a byte. There is no actual standard that defines how many bits are in a byte, but it has become something of a de facto standard.

How many bits are in a byte?

In the most common definition, there are 8 bits in one byte. One bit is either a flow of electricity or no electricity. This written as 0 or 1. There are four bits in a nibbl

How many bits are in a byte in a computer?

There are 8 bits in a byte.  People use a lowercase 'b' to mean "bits" and an uppercase "B" to mean bytes. So if a hard drive has 500GB, that's giga-bytes. But if a networ

How many bytes are in 1 bit?

Bit is the smallest component of data and byte is larger then bit so: 1 byte = 8 bits = 23 bits 1 Kilobyte = 1024 bytes = 210 bits 1 Megabyte = 1024 kilobytes = 220 bits

What is a byte and how many bits does it contain?

  A byte is the basic unit of information in a computer. It is usually the smallest addressable object in memory.   The size of a byte is a function of the design of th

What is a bit in a byte?

Since 8 bits make a bite then a bit is one-eight of a bite.

How many bytes in 16 bits?

i dont think there are any. i think its about two different things   edit: there are 2: 1 byte = 8 bits

How many bytes are in one bit?

  This question has things a little bit backwards.   One byte usually consists of 8 bits (one bit is one "BInary digiT" -- either a 0 or a 1).   Half a byte (4 bits)

How many bits is 1k byte?

One BYTE is currently defined as 8 BITs. (Binary digITs)   1 B = 8 b   (Big "B" is for Bytes and little "b" is for bits.)    Some data protocols use a different
