In computers, 1kb is equal to 1024 bytes. kB refers to kilobytes, which is a unit of information measurement and is a multiple of the computer data storage unit byte; according to the IEC naming standard, 1kB = 1024B (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. One byte stores an 8-bit unsigned number.

KB (kilobyte (unit of measurement))
kB (Kilobyte) is an information measurement unit and is the storage unit of computer data memory in bytes Multiple forms of . Nowadays, it is usually used to identify the storage capacity of storage media with general capacity such as memory.
According to the IEC naming standard, the standard naming for binary storage units is KiB, MiB, etc., 1kiB = 1024B. This is determined by the binary storage method of the data stream.
Linux and macOS X use the International System of Units standard naming. However, systems below Windows xp still incorrectly label KiB as KB. Confusion has become common because systems still record data capacity in the old way, usually Kilobyte can also refer to Kibibyte, that is, 1KB = 1024B.
Byte
Byte is a unit of measurement used by computer information technology to measure storage capacity. It is also Represents data types and language characters in some computer programming languages.
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.
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.

B and bit
Data storage is in "byte" (Byte), and data transmission is mostly in " "Bit" (also known as "bit") is the unit. One bit represents a 0 or 1 (that is, binary). Every 8 bits (bit, abbreviated as b) constitute a byte (Byte, abbreviated as B). It is the smallest level of information unit.
Word
In a computer, a string of numbers that are processed or calculated as a whole is called a computer word, or word for short. 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 a computer is called the word length. The calculated word length refers to the number of binary digits it can process at one time. 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.
