ASCII: 128; 95 printable, 33 control
iso-8859-1: 256; 191 printable, 65 control
unicode: many
ASCII (American Standard Code for Information Interchange) is a character-encoding scheme that was standardised in 1963. There is no encoder required to create ASCII. Every machine supports it as standard, although some implement it via UNICODE. The only difference is in the number of bytes used to represent each character. The default is one byte per character yielding 128 standard encodings that map exactly with the first 128 characters in UNICODE encoding.
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.
There are primarily two types of ASCII code: standard ASCII and extended ASCII. Standard ASCII uses 7 bits to represent 128 characters, including control characters, digits, uppercase and lowercase letters, and some symbols. Extended ASCII expands this to 256 characters by using the 8th bit, allowing for additional characters, symbols, and graphical representations, which vary by encoding system. Common extended ASCII sets include ISO-8859-1 and Windows-1252, which accommodate various languages and special characters.
Unicode is a character encoding standard that aims to represent text in all writing systems worldwide. It allows for the encoding of characters from different languages and symbols in a single standard. Unlike ASCII, which is limited to only 128 characters, Unicode supports over 143,000 characters.
128
Standard ASCII (American Standard Code for Information Interchange) uses 7 bits to represent characters, allowing for 128 unique symbols, which include control characters and printable characters like letters, digits, and punctuation. Extended ASCII, on the other hand, uses 8 bits, enabling 256 characters, which includes the original 128 standard ASCII characters plus an additional set of 128 characters for various symbols, accented letters, and graphics, varying by specific encoding schemes like ISO-8859-1 or Windows-1252. This expansion allows for better support of international languages and special symbols.
ASCII stands for American Standard Code for Information Interchange. It provides a means to facilitate communication on computers. It has 128 characters.

Those pictures are called ASCII art. They are created using characters from the ASCII standard to form images or designs.
ASCII (American Standard Code for Information Interchange) is a character encoding standard that represents text in computers and other devices. However, ASCII primarily supports the English alphabet and does not include characters specific to the Kannada language. For Kannada, other encoding systems like UTF-8 or ISCII are used, which can represent a wider range of characters, including those used in Kannada script. These encodings enable proper display and manipulation of Kannada text in digital formats.
ASCII, or the American Standard Code for Information Interchange, originally defined 128 characters, using 7 bits for encoding. However, the extended version, known as Extended ASCII, uses 8 bits, allowing for 256 characters (2^8 = 256). This extension includes the original 128 ASCII characters plus an additional set of 128 characters, which include various symbols, letters from different languages, and graphical characters. The use of 8 bits became a standard in many systems, accommodating a broader range of characters for diverse applications.
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.
