A document version?
A document version is an initial release (or complete re-release) of a document, as opposed to a revision resulting from issuing change pages to a previous release.
VDD
"VDD" is an acronym that stands for "version description document".
A version description document (VDD)
Version description document (VDD) is a document that accompanies and identifies a given version of a software product. Typically the VDD includes the description and identification of the software, identification of the changes incorporated into this version, and the installation and operating information unique to this version of the software.
A vertical microinstruction
A vertical microinstruction is a microinstruction that specifies one of a sequence of operations needed to carry out a machine language instruction. Vertical microinstructions are short, 12 to 24 bit instructions. They're called vertical because they are normally listed vertically on a page. These 12 to 24 bit microinstructions instructions are required to carry out a single machine language instruction. In addition to vertical microinstructions, there are horizontal and diagonal microinstructions as well.
A virtual address
In virtual storage systems, virtual addresses are assigned to auxiliary storage locations. The use of virtual addresses allow those locations to be accessed as though they were part of the main storage.
A virtual memory
Virtual memory relates to virtual storage. In virtual storage, portions of a user's program and data are placed in auxiliary storage, and the operating system automatically swaps them in and out of main storage as needed.
A waiver
In software QA, a waiver is an authorization to accept software that has been submitted for inspection, found to depart from specified requirements, but is nevertheless considered suitable for use "as is", or after rework by an approved method.
