Introduction:

The unit bit of data storage is the smallest unit of information, which has only two binary states: 0 and 1. The smallest unit of information in a computer is bits, that is, binary bits, and eight bits make up a byte, that is, a byte.

Bytes are the basic unit of data in a computer. All kinds of information need at least one byte to be stored and processed in the computer. For example, an ASCII code is represented by one byte and a Chinese character is represented by two bytes.

A byte is 8 bits, an English letter usually takes up one byte, and a Chinese character usually takes up two bytes. The smallest unit of information that ordinary computer systems can read and locate is bytes, that is, in fact, ordinary computer systems cannot accurately read and locate bit-level information.

In the binary number system, each 0 or 1 is a bit, and the number of CPU bits of a computer refers to the maximum number of bits that the CPU can handle at a time. For example, the CPU of a 32-bit computer can process up to 32-bit data at a time.

Bit, the abbreviation of binary number, is a term put forward by mathematician John Wilder Tukey (it may have been put forward by 1946, but it is reported that it was put forward by 1943). This term was first formally used in Shannon's famous literary work Information Theory, that is, Mathematical Theory of Communication.

Introduction of storage unit:

The unit of storage is the unit of measurement. Refers to taking a specific quantity or standard as a recording (counting) point in a certain field. Then use the multiple of this point to define another point, which is synonymous with counting unit or storage unit.

Storage unit:

The basic unit of computer storage information is called storage unit, each storage unit is a binary bit, and one bit can store a binary number 0 or 1. Every 8 bits make up a byte. Since the 8086CPU is a 16-bit data bus, its word length is 16 bits and consists of 2 bytes.
