Several coding techniques have been invented that represent alphanumeric information as a series of l's and O's.
ASCII and EBCDIC codes are the two most widely used alphanumeric codes. The ASCII Code is very popular code used in all personal computers and workstations whereas the EBCDIC code is mainly alphanumeric code, the UNICODE, has evolved to overcome the limitation of limited character encoding as in case of ASCII and EBCDIC code.
The American Standard-Code for Information Interchange (ASCII) pronounced "as-kee" is a 7-bit code based on the ordering of the English alphabets.
It is a seven-bit code, it can almost represent 128 characters. These include 95 printable characters including 26 upper-case letters (A to Z) , 26 lowercase letters (a to z) , 10 numerals (0 to 9) and 33 special characters such as mathematical symbols, space character etc.

But now ASCII code is available with 8 bits coding system by which we can represent 256 character.
