This document discusses character encoding systems used to represent textual data in computing. It describes several character encoding standards including ASCII, EBCDIC, ISO 646, ISO 885, and UTF-16. ASCII is a 7-bit encoding that can represent 128 characters and was limited as it does not support languages with large character sets. EBCDIC is an 8-bit encoding mainly used on IBM mainframe computers. UTF-16 is a 16-bit Unicode encoding that can represent over 65,000 characters and supports representation of text in many languages.

2.  In computing, a character encoding is used to
represent a repertoire of characters by some kind
of an encoding system.
 A character encoding is used in both computation,
data storage, and transmission of textual data.
 Terms such as character set, character map,
code set or code page are sometimes used as near
synonyms; however, these terms have related but
distinct meanings described in the article.

3.  ISO 646
 ASCII
 EBCDIC
 CP37
 CP930
 CP1047
 ISO 885

4.  Windows-1251 for Cyrillic alphabets
 Windows-1252 forWestern languages
 Windows-1253 for Greek

5.  The American Standard Code for Information
Interchange is a character-encoding scheme
originally based on the english alphabet that
encodes 128 specified characters

6.  Developed by x3 – American Standards
Association
 7 bit character encoding system
 It uses 7 bits for representing a character.
 It can express maximum of 128 characters
including characters, punctuations, special
characters.

7.  Limitations of ASCII:
The 8-bit ASCII notation is sufficient for
many practical applications in ENGLISH
language or other languages having a smaller
number of alphabetic.
 However, there are languages which have
more than 256 alphabetic, typical examples
are Far Eastern languages like CHINEESE,
JAPANEESE, and KOREAN.

8.  Extended binary coded decimal interchange
code.
 8 bit character encoding standard.
 Mainly used in IBM mainframe computers.

9.  Assign unique code for each and every
character.
 It can be used in any platform.
 Contains 1,10,000 charcters covers 100 scripts
 Developed by joe beeker , lee collins, mark
davis of xerox company.
 It is a 16 bit representation of a character
 Other versions are
▪ UTF -8 (Unicode Transformation Format)
▪ UTF-16 (Unicode Transformation Format)

10.  It may contain 216 = 65536 patterns.
 That can interpret alphabetic of any language
or in fact of many languages
