ASCII stands for American Standard Code for Information Interchange. It provides a means to facilitate communication on computers. It has 128 characters.

200 characters is 200 characters, unless you are talking about Unicode (which isn't Ascii).

ASCII standardizes characters between 0 and 127.
Extended ASCII is 8-bit encoding which is wider than standard ASCII and also includes all characters from standard ASCII encoding.ASCII is 7-bit, 128 possible values; Extended ASCII is 8-bit , 256 possible value;128 first characters of Extended ASCII is the same as ASCII, next 128 are additional. This why it is called Extended ASCII.What is ASCII?ASCII is mainly English language characters encoding, that is used for representation of text information.
First of all ASCII is encoding system that tells how binary data from file could be represented as text. Is was and still is very widely used starting 1960s. Standard ASCII encoding is 7-bits encoding allowing 128 values, while Extended ASCII is 8-bits encoding which allows 256 values, that is 128 more characters in the table. First 128 Extended ASCII table characters is the same as ASCII table, next 128 is additional characters.
The ASCII code uses seven-bit patterns to denote 128 different characters. Ten of the characters are decimal digits 0 to 9. The higher order bits have the same pattern for all 10 digits. Each digit is identified by the low-order four bits using the binary patters of these digits. Capital and lowercase letters are encoded in a way that makes sorting of textual information easy.
one of the major difference b/w ISCII and ASCII is that ASCII offers a larger range of characters than ISCII.
That's because the inventor of ASCII code thought they are important characters.

The ASCII HEX Encoded/Binary String method of obfuscation has been very popular, although there are new methods that have been suggested. By using the ASCII HEX Encoded/Binary String method, the resulting code injection is difficult to identify as a threat.
ASCII only has 127 standard character codes and only supports the English alphabet. While you can use the extended ASCII character to provide a set of 256 characters and thus support other languages there's no guarantee that other systems will use the same code page, so the characters will not display correctly across all systems (the characters you see will depend upon which code page is currently in use). Moreover, some languages, particularly Chinese, have thousands of symbols that simply cannot be encoded in ASCII. UNICODE encoding supports all languages and the first 127 symbols are also the same as ASCII, so all characters appear the same across all systems. UTF8 is the most common UNICODE encoding in use today because it uses one-byte per character for the first 127 characters and is therefore fully compliant with non-extended ASCII. If the most-significant bit is set then the character is represented by 2 or more bytes, the combination of which maps to the UNICODE encoding.
