The IBM Jargon and Computing Dictionary
This is the tenth edition of the "IBM Jargon and General Computing Dictionary," dated May 1990.

The items in this dictionary were selected from the huge vocabulary of computer-related terms used in IBM. To be included here, a word or phrase must either have originated in IBM, or (more commonly) its meaning or usage in IBM must be different from the usual.

​Acronyms and abbreviations are not included except where they are necessary for cross-references, or are used as true words in their own right (for example, “APAR”).
