A scheme that encodes 128 specified characters -- the numbers 0-9, the letters a-z and A-Z, some basic punctuation symbols, some control codes that originated with Teletype machines, and a blank space -- into the 7-bit binary integers. Forms the basis of the character set representations used in most computers and many Internet standards. [FP001] (See: code.)
