''This is the standard IBM SDK/DDK Glossary that is used by multiple documents including the [[Virtual Device Driver Reference for OS/2]], [[MMPM/2 Device Driver Reference]], [[Display Device Driver Reference for OS/2]], [[Virtual Device Driver Reference for OS/2]], [[Printer Device Driver|Printer Device Driver Reference for OS/2]], [[Storage Device Driver Reference]], GRADD Reference Glossary, [[Input Output Device Driver Reference]] and others.''

This glossary contains terms and definitions that are, for the most part, used for OS/2 products. This is not a complete dictionary of computer terms.

==Introduction==
This glossary defines many of the terms used in this book. It includes terms and definitions from the ''IBM Dictionary of Computing'', as well as terms specific to the Presentation Manager, but it is not a complete glossary for OS/2.

Other primary sources for these definitions are:

*The ''American National Standard Dictionary for Information Systems'', ANSI X3 .172-1990, copyrighted 1990 by the American National Standards Institute, 11 West 42nd Street, New York, New York 10036. These definitions are identified by the symbol (A) after the definition.
*The ''Information Technology Vocabulary'', developed by Subcommittee 1, Joint Technical Committee 1, of the International Organization for Standardization and the International Electrotechnical Commission (ISO/IEC JTC1/SC1). Definitions of published parts of this vocabulary are identified by the symbol (I) after the definition; definitions taken from draft international standards, committee drafts, and working papers being developed by ISO/IEC JTC1/SC1 are identified by the symbol (T) after the definition, indicating that final agreement has not yet been reached among the participating National Bodies of SC1.
