The basic unit of computer memory storage capacity is "byte". The number of storage units contained in the memory is called storage capacity, and its basic unit of measurement is "byte", which is Byte in English; one byte stores an 8-bit unsigned number, and the stored value range is "0-255". 8 binary bits are called 1 byte, that is, "1Byte=8bit".
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
The smallest unit of computer storage data is bit, The basic unit of storage capacity is byte. The smallest unit of computer storage data, the English name is bit, also called bit.
The number of storage units contained in the memory is called storage capacity, and its basic unit of measurement is byte, English Byte. Abbreviated as B.
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.
Eight binary bits are called 1 byte. In addition, there are KB, MB, GB, TB, etc. The conversion relationship between them is 1Byte=8bit, 1KB=1024B, 1MB=1024KB, 1GB= 1024MB, 1TB=1024GB.
Extended knowledge:
Bytes are 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.

Data storage is in "byte" (Byte), and most data transmission It is based on "bit" (also known as "bit"). One bit represents a 0 or 1 (that is, binary). Every 8 bits (bit, abbreviated as b) constitute a byte (Byte, abbreviated as B), is the smallest level of information unit.
Word (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.
