Binary code: ASCII "Ass Kee"
(http://www.telacommunications.com/nutshell/ascii.htm#chart)
ASCII, pronounced "ask-ee" is the acronym for
American Standard Code for Information Interchange. It's a set of characters which,
unlike the characters in word processing documents, allow no special formatting
like different fonts, bold, underlined or italic text. All the characters used
in email messages are ASCII characters and so are all the characters used in
HTML documents. (Web browsers read the ASCII characters between angle brackets,
"<" and ">", to interpret how to format and display HTML documents.)
An "ASCII file" is a data or
text file that contains only characters coded from the standard ASCII character set.
Characters 0 through 127 comprise the Standard ASCII Set and characters
128 to 255 are considered to be in the
Extended ASCII Set.
These codes, however, may not be the same in all computers and files containing these
characters may not display or convert properly by another ASCII program.
Knowing something about ASCII can be helpful.
ASCII files can be used as a common denominator for data conversions. For example,
if program A can't convert its data to the format of program B, but
both programs can input and output ASCII files, the conversion may be possible.
ASCII characters are the ones used to send and receive email. If you're familiar
with email, you already know that formatting like italic type and underlines are
not possible. Email transmissions are limited to ASCII characters and because
of that, graphics files and documents with non-ASCII characters created in
word processers, spreadsheet or database programs must be "ASCII-fied" and
sent as email file attachments. When the files reach
their destination they are "deASCII-fied" (i.e. decoded) and therefore,
reconstructed to restore them for use.
