What Is Binary Encoding? Binary encoding is a procedure to convert data to a form that allows the data to be easily used by difference computer operating systems. This achieved by converting binary data to a ASCII string format, specifically, converting 8-bit data into a 7-bit format, that use as standard set of ASCII printable characters. ASCII, American Standard Code for Information Interchange, was developed by AT&T in the early 1960s And is the most widely used character encoding format. Modern character encoding continues to be base on ASCII although it support many additional characters and different languages.
