Which of the following is NOT a method for encoding text characters on a computer?

• ANSI
• ASCII
• SIX-BIT
• EBCDIC 

EXPLANATION

EBCDIC encoding. EBCDIC, in fullextended binary-coded decimal interchange code., Data-encoding system, developed by IBM, that uses a unique eight-bit binary code for each number and alphabetic character as well as punctuation marks and accented letters and non-alphabetic characters. 

ANSI encoding. ANSI encoding is a slightly generic term used to refer to the standard code page on a system, usually Windows. ... This is essentially an extension of the ASCII character set in that it includes all the ASCII characters with an additional 128 character codes.

ASCII, abbreviated from American Standard Code for Information Interchange, is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices.

A six-bit character code is a character encoding designed for use on computers with word lengths a multiple of 6. Six bits can only encode 64 distinct characters, so these codes generally include only the upper-case letters, the numerals, some punctuation characters, and sometimes control characters.
