WebASCII uses 7 bits of an byte to represent a character ASCII can represent 128 characters ASCII sets the most significant bit as a parity bit or as 0 Extended ASCII uses the most... ASCII was first used commercially during 1963 as a seven-bit teleprinter code for American Telephone & Telegraph's TWX (TeletypeWriter eXchange) network. TWX originally used the earlier five-bit ITA2, which was also used by the competing Telex teleprinter system. Bob Bemer introduced features such as the escape sequence. His British colleague Hugh McGregor Ross helped to popularize this work – according to Bemer, "so much so that the code that was to bec…

WebBecause ASCII is a 7-bit encoding, ASCII characters are limited to the lowest 128 Unicode characters, from U+0000 to U+007F. If you use the default encoder returned by the Encoding.ASCII property or the ASCIIEncoding constructor, characters outside that range are replaced with a question mark (?) before the encoding operation is performed. WebThe ASCII table has 128 characters, with values from 0 through 127. Thus, 7 bits are sufficient to represent a character in ASCII; however, most computers typically reserve 1 byte, (8 bits), for an ASCII character. One byte allows a numeric range from 0 through 255 which leaves room for growth in the size of the character set, or for a sign bit. microchips in human brains
