Byte is a common unit in computers, and its English name is "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 the unit of binary data. One byte stores an 8-bit unsigned number, and the stored value range is 0-255.

"Byte" is a commonly used unit in computers. Its English name is "Byte" and is commonly represented by the capital letter B. For example, the combined units of KB, MB, GB, and TB are Kilobytes (KiloByte) respectively. , MegaByte, GigaByte, TeraByte.
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. One byte stores an 8-bit unsigned number, and the stored value range is 0-255. Like characters, byte type variables only require one byte (8 bits) of memory space to store
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.

B and bit
Data storage is in "bytes" ( Byte) as the unit, data transmission is mostly in "bit" (also known as "bit"). One bit represents a 0 or 1 (ie binary), and each 8 bits (bit, abbreviated as b) is composed of A byte (Byte, abbreviated as B) is the smallest unit of information.
Word
In a computer, a string of numbers that are processed or calculated as a whole is called a computer word. Abbreviation word. Words are usually divided into bytes (each byte is usually 8 bits). In memory, each cell typically stores one word. Therefore each word is addressable. The length of a word is expressed in bits.
Word length
The number of bits contained in each word of the computer is called the word length. The calculated word length refers to the number of digits it can hold at one time. The number of binary digits processed. Generally, the word length of large computers is 32-64 bits, that of small computers is 12-32 bits, and that of microcomputers is 4-16 bits. Word length is an important factor in measuring computer performance.
Unit conversion
1 byte (Byte) = 8 bits (bit)
1KB (Kilobyte, kilobyte) = 1024B
1MB (Megabyte, megabyte) = 1024KB
