ASCII is a computer coding system based on the Latin alphabet, which is mainly used to display modern English and other Western European languages. It is now the most versatile single-byte encoding system and is equivalent to ISO/IEC 646. In a computer, all data is stored and computed using binary numbers (because the computer represents 1 and 0, respectively, with high and low levels), for example, 52 letters (including uppercase) such as a, B, C, D, and 0, 1, and other commonly used symbols (such as *, #, @ And so on in the computer is also used to store the binary number to represent, and specifically which binary numbers to indicate which symbol, of course, everyone can contract their own set (this is called code), and if you want to communicate with each other without causing confusion, then we must use the same coding rules, So the United States, the standardization of the introduction of the ASCII code, unified rules of the above-mentioned symbols with which binary numbers to represent. The American Standard Information Interchange code is a standard single-byte character encoding scheme developed by the American National Standards Institute for text-based data. It began in the late 50 and was finalized in 1967. It was originally the United States national standard, for different computers to communicate with each other as a common code of the West character coding standards, it has been established by the International Organization for Standardization, known as the ISO 646 standard. Applies to all Latin letter characters. The ASCII code uses the specified 7-bit or 8-bit binary number combination to represent 128 or 256 possible characters. The standard ASCII code is also called the base ASCII code, using a 7-bit binary number to represent all uppercase and lowercase letters, numbers 0 through 9, punctuation, and special control characters used in American English.
