An A to Z glossary of computer- terms has been posted on Apple's Web site.

The glossary supplies a comprehensive list of definitions – from "A Frame" to "Zip disk".

It also includes obscure explanations, such as "XOFF: An ASCII character that tells the transmitting device to halt transmission", as well as common terms, such as Delete – “A key that you can press in some applications to erase the character to the left of the cursor.”
