-[Acronym] for American Standard Code for Information Interchange . A standard mapping between characters and bit patterns (7 bits, to be exact .)  
-Many 8-bit codes (such as [ISO] 8859-1, the [Linux ] default character set ) contain ASCII as their lower half. The international counterpart of ASCII is known as ISO 646
+An [Acronym] for __A__merican __S__tandard __C__ode for __I__nformation __I__nterchange .  
+The [ANSI] X3.4 standard specifying a character set with 95 characters with codes ranging from 32 to 126 (0x20-0x7E). The codes from 0 to 31 have come to be known as control characters and are not specified by [ASCII] . Neither is any code beyond 126, since [ASCII] was designed strictly as a 7-bit encoding. It was published in 1968 and is by far the most successful and popular encoding ever conceived.  
+Almost all 8-bit encodings (such as [ISO] 646 and the wildly popular [ISO ] 8859 tables ) contain [ ASCII] as their lower half. The only exception with any wide acceptance at all is [EBCDIC]
