Relationship between bit, byte, bit, byte, and Chinese Character

Byte: Generally, an 8-bit binary string that can represent common English characters is called one byte.

An English letter (case-insensitive) occupies the space of one byte, and a Chinese character occupies the space of two bytes.
Symbol: English Punctuation 2 occupies one byte, and Chinese Punctuation occupies two bytes.

1 byte = 8 bits)

Bit, also known as binary bit. New Hong Kong and Taiwan: RMB

BITs are the smallest unit of binary information.
1 bit is 1 bit

 

 

Bytes

Byte: bytes are the units in which information is transmitted over the network (or stored in hard disk or memory.
Byte is a unit of measurement used by Computer Information Technology to measure storage capacity and transmission capacity. one byte is equal to eight-bit binary.
In ASCII code, an English letter (case-insensitive) occupies the space of one byte, and a Chinese character occupies the space of two bytes.
Symbol: English Punctuation occupies one byte, and Chinese Punctuation occupies two bytes. For example, the English period "." occupies the size of 1 byte and the Chinese period "." Size of 2 bytes
A sequence of binary numbers, which is generally an 8-bit binary number as a numerical unit in a computer. For example, an ascii code is a byte. The conversion of such units is:
1 gib (TB, terabyte) = 1024 gib (40 to the power of 2)
(1 TB = 1024 GB)
1 gib (GB, gigabyte) = 1024 MB (2 to the power of 30 bytes)
(1 GB = 1024 MB)
1 MB (megabyte) = 1024 kilobytes (20 to the power of 2)
(1 MB = 1024kb)
1024 bytes (kb, kilobyte) = bytes (10 to the power of 2) (1kb = 1024b)
1 byte = 8 bits)
Note: TB is the largest storage unit on the hard disk. 10 TB is about the size of a person's brain.
Larger unit: petabyte (petabyte, 1pb = 1024 TB), EB (exabyte, 1eb = 1024pb), ZB (zettabyte, 1zb = 1024eb), Yb (yottabyte, 1yb = 1024zb )......

Character

A character is an abstract entity that can be expressed using multiple character schemes or code pages. For example, Unicode UTF-16 encoding represents a 16-bit integer sequence, while Unicode UTF-8 encoding represents the same character as an 8-bit sequence. The Common Language Runtime uses Unicode UTF-16 (UNICODE conversion format, 16-bit encoding form) to represent characters.
Applications targeting the Common Language Runtime Library use encoding to map the character table format from the local character scheme to other schemes. The application uses decoding to map characters from a non-local program to a local program.
Computer and communication devices use character encoding to express characters. It means that a character is specified to a certain West. Traditionally, it represents a full number of bitwise sequences. In this way, the data can be transmitted over the network and stored conveniently. Two common examples are ASCII and UTF-8 for unified code. According to Google's statistics, UTF-8 is currently the most commonly used in the coding of web pages. [1] compared to most character encodings, the moss password maps the characters to numbers or bits, and represents the characters using a sequence of electronic pulses of an indefinite length.
To find out the characters, you want to find out the characters. What are the characters you asked? So why don't you ask what words are? It is like a general term.

Bit in Computer

In a binary system, each 0 or 1 is a bit, which is the minimum unit of data storage. 8 bits are called a byte ). The number of CPU bits in a computer indicates the maximum number of CPU bits that can be processed at a time. For example, the CPU of a 32-bit computer can process up to 32-bit data at a time.

Bit

1) computer terminology refers to the unit of information, which is a transliteration of English bit. The information contained by a binary number is one bit. For example, 0101 of the binary number is four bits.
2) the bit in the binary number, the unit of measure of the amount of information, is the minimum unit of the amount of information. Digital audios use electric pulses to express audio signals. "1" indicates a pulse, and "0" indicates a pulse interval. If the information of each vertex on the waveform is represented by code in a group of four digits, it is called 4 bits. The higher the bit number, the more accurate the analog signal expression, and the stronger the ability to restore the audio signal.
