-[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]
.
