What are binary coding schemes. Name and describe three.

Binary coding schemes are used to represent characters in a numeric format that can be processed by a digital computer.

ASCII – American Standard Code for Information Interchange – an 8 bit scheme that can represent 2^8^th different characters (256).  It is often used on microcomputers.

EBCDIC – Extended Binary Coded Decimal Interchange Code is also an 8 bit code created by the IBM Corporation, and typically used on mainframe computers

Unicode – a 16 bit encoding scheme that can represent 2^16^th different characters (65,536), therefore it can be used for international languages such as Chinese and Japanese
