What is UTF-8 Encoding?
UTF-8 is a character encoding standard used to convert characters from the Unicode character set into machine-readable binary data. UTF-8 is a variable-length encoding that flexibly adjusts storage space based on the encoding length of different characters, making it widely used in international and multilingual scenarios.
What is ASCII Code?
ASCII code is a character encoding standard based on the Latin alphabet, where each character is mapped to a unique numerical code. Originally designed for transmitting text information in computer systems, ASCII code uses only 7 bits of binary (0~127), allowing representation of only 128 characters.
What is the Unicode Character Set?
Unicode is a character encoding standard that defines a unified encoding method for all characters worldwide. The Unicode character set includes over 130,000 characters, covering almost all languages and symbols. There are various encoding methods for the Unicode character set, such as UTF-8, UTF-16, etc.
What are Half-width and Full-width Characters?
Half-width and full-width characters are concepts used to represent the space occupied by characters. Half-width characters refer to characters like English letters, numbers, and punctuation, which have a width of one character. Full-width characters, on the other hand, refer to Chinese characters, Japanese kana, etc., which have a width of two characters. In computer systems, the storage space and display width occupied by half-width and full-width characters are different.
What is Binary Number?
Binary numbers are a numerical system that consists of only 0s and 1s. In computers, all data is stored and processed in the form of binary numbers. Binary numbers can be manipulated through bitwise operations such as AND, OR, XOR, etc., forming a fundamental concept at the core of computer systems.
What is Byte Order?
Byte order refers to the way multiple bytes are arranged in sequence. In different computer architectures, byte order may vary, such as little-endian and big-endian. The correctness of byte order is crucial for scenarios like network communication and cross-platform development.
What is Encoding?
Encoding is the process of converting symbols from a symbol system into machine-readable binary data. Common encoding methods include ASCII, UTF-8, GBK, etc. Encoding plays a crucial role in computer systems, affecting the transmission and storage of various types of data, such as text, audio, and video.
