In computers, the basic unit of storing information is "Byte", that is, byte. Byte is a unit of measurement used by computer information technology to measure storage capacity, a unit of binary data; 1 byte is composed of 8 binary bits and can store 8-bit unsigned numbers.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

In computers, the basic unit of storing information is "Byte", that is, byte.

One Byte=8bit, that is, one byte is equal to eight binary bits.

Byte (Byte) is a unit of measurement used by computer information technology to measure storage capacity. It also represents data types and language characters in some computer programming languages. Byte is an unsigned type from 0-255, so it cannot represent negative numbers.

Byte is the unit of binary data. A byte is usually 8 bits long. However, some older computer architectures use different lengths. To avoid confusion, in most international literature the word byte is used instead of byte. In most computer systems, a byte is an 8-bit unit of data. Most computers use a byte to represent a character, number, or other character. A byte can also represent a series of binary bits. In some computer systems, 4 bytes represent a word, which is the unit of data that the computer can efficiently process when executing instructions. Some language descriptions require 2 bytes to represent a character, which is called a double-byte character set. Some processors are capable of handling double-byte or single-byte instructions. Bytes are often abbreviated as "B" and bits are often abbreviated as a lowercase "b". The size of computer memory is usually expressed in bytes.

The unit of bytes is too small in actual use. Commonly used units larger than bytes are:

  • 1KB (kilobytes) = 1024Byte

  • 1MB (megabytes) = 1024KB

  • 1GB (gigabytes) = 1024MB

  • 1TB (terabytes) = 1024GB
