ASCII was oringinally developed to use only 8 bits. This was standard on the Commodore 64 and like computers during that era. The industry standard has never changed.
You have command sequences such as ASCII (13) meaning Return in the lower numbers. Characters start at ASCII (32) with the Space and go up to about the 120's. Afterwards it's special characters.
When I programmed in BASIC I used to use ASCII symbols to make games and drawings.
On older systems you could hold in the ALT key and type an ASCII number on the keypad to get the corresponding character.

As ASCII is an 8 bit coding scheme the maximum number of unique representations of characters is 256 which encompass the numbers 0 through 255. Many of these characters or unviewable or unprintable and are used for control purposes. More characters can be represented if certain characters are reserved as control and are used PRIOR to certain other nonpritable codes to signify that the character set has shifted. For example, an ASCII code 27 DEC is used to signify that something special is about to happen, and the NEXT character tells the system WHAT is about to happen.

ASCII can represent 128 values, extended ASCII code can represent 256.

ASCII has been expanded to an 8- bit version, allowing 128 additional values

ASCII can represent a total of 256 characters. (2^8)

128 characters. And there is some 'ASCII extended code or something' which can represent 256 characters.

By definition , It *can* represent 256 values ( 2^8 = 256)

256. Enough for the standard western character set, but no more. Which is why the world is now moving to Unicode, which can cope with all the alphabets in the world - 100,000 characters already defined and plenty of space for more.
