ASCII stands for American Standard Code for Information
Interchange. Computers can only understand numbers, so an ASCII code is
the numerical representation of a character such as 'a' or '@' or an
action of some sort. ASCII was developed a long time ago and now the
non-printing characters are rarely used for their original purpose.
Below is the ASCII character table and this includes descriptions of the
first 32 non-printing characters. ASCII was actually designed for use
with teletypes and so the descriptions are somewhat obscure. If someone
says they want your CV however in ASCII format, all this means is they
want 'plain' text with no formatting such as tabs, bold or underscoring
- the raw format that any computer can understand. This is usually so
they can easily import the file into their own applications without
issues. Notepad.exe creates ASCII text, or in MS Word you can save a
file as 'text only'
