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' |

Extended ASCII
Codes
As people
gradually required computers to understand additional
characters and non-printing characters the ASCII set became
restrictive. As with most technology, it took a while to get a
single standard for these extra characters and hence there are
few varying 'extended' sets. The most popular is presented
below. |

as many as you can. Click restart to clear the boxes and
try again. Good luck!
