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

What is a byte and a bit?

Answer A byte is made up of eight bits. A bit is a single state, usually represented by a 0 or a 1. Using binary code, eight bits can be used to represent characters numbers and other items. A bit is a single numeric value, either '1' or '0', that encodes a single unit of digital information. A b (MORE)

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 nibble and two nibbles in a byte. 8 bits = 1 byte. 1024 bytes = 1KB 1024 KB = 1 MB 1024 MB = 1 GB

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

Why a byte is equal to eight bits?

A byte is eight bits because in the 1960s, the most popular processors used 8-bit registers which allowed them to manipulate 8 bits at a time. This common usage of the term byte eventually became the standard due to its widespread usage.

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) is sometimes referred to as a nybble or nibble.

Why 1 byte 8 bits?

The earliest computers could only send 8 bits at a time, it was only natural to start writing code in sets of 8 bits. This came to be called a byte. It's essentially arbitrary, however 8 bits was initially a good fit since it was able to easily fit all letters, upper and lower case, plus all punct (MORE)

How many bits in byte?

historically, the byte was whatever the computer said it was. There have been computers that use bytes anywhere from 5 to 36 bits long. Today however, almost all computers use 8 bit bytes. When there is absolutely no room for misunderstanding, the term octet is used instead, which always means 8 bit (MORE)

What is difference between bit and byte?

the bit is first smalest than a byte and a bit in computation is used to refer to a data transfer and byte an amount of data store ex i downloud 380 bytes at 4 bits per second

What do these bits and bytes measure?

They Measure Computer Memory in Binary. Binary is Computer Code In Only 0 & 1 's. 1 bit = one 0 or 1 1 byte = 8 bits 8 bits or 1 byte = a group of eight 0 & 1 's

1 bytes is equal to how many bits?

One byte is usually 8 bits , but some computer systems used a 9-bit byte. A bit is a Binary digit. (0 or 1) And a nibble is a 4- bit byte. Sometimes used in simple machines such as washing machine or toaster. Back in early telegraphy days, paper tape was used for machine telegraphy. Its d (MORE)

What is a bit and how many are in a byte?

A bit (contraction of binary digit) is the basic unit of information in computing and telecommunications; it is the amount of information stored by a digital device or other physical system that exists in one of two possible distinct states. Old Standard bit b 0 or 1 byte B 8 bits IEC Sta (MORE)

How many bits are in a byte of binary data?

One BYTE is always 8 BITs. (Binary digITs) Some data protocols use a different number of bits to define a character, most systems today use 8 bits, some older systems used 5 bits or 7 bits. But a BYTE is always 8 bits regardless. (a NIBBLE is half a byte - 4 bits)

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 = 2 3 bits 1 Kilobyte = 1024 bytes = 2 10 bits 1 Megabyte = 1024 kilobytes = 2 20 bits 1 Gegabyte = 1024 megabytes = 2 30 bits

How do you find out how many byte in 64-bit computer?

right click on my computer, click on properties, click on general tab. at the bottom you will see your memory in mega bytes or giga bytes. . or, right click on the start bar, left click on task manager, click on the performance tab and where it says physical memory there will be a total. this will (MORE)

1kilo byte how many bits?

There are 1,024 bytes in a kilobyte. There are 8 bits in a byte, so there are 8,192 bites in a kilobyte.

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.)

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 the computer, but nearly universally, it has come to mean 8 bits. (Octet is a more precise definition of 8 bits of memory, in case there (MORE)

Describe the purpose of bits and bytes?

A bit is the smallest unit of data that a computer can record. It can have only of of two values; a bit is either on (1) or off (0). A byte is the smallest addressable unit if memory in a computer.

How many bits in 20 mega bytes?

8 bits=1 byte, 1024 bytes=1 kilobyte, 1024 kilobytes=1 megabyte. . So the way to solve this is to do this: 8x1024x1024x20. . This equals 167,772,160 bits in 20 megabytes. . Hope that helps! . - ElectroGoofy

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 network cable lists its speed as 10Mbps, that means 10 mega- bits per second.

What are Bits vs Bytes?

To explain this, lets think of a text document. When you press a key on the keyboard, a series of 8 "switches", either on of off, represented by 1's and 0's, are switched and sent to the document. each one of these "switches" is called a bit. 8 bits make one unit of data, a byte. The abbreviations (MORE)
