Valgrind – Valgrind is a free programming tool for memory debugging, memory leak detection, and profiling. Valgrind was originally designed to be a free version of Purify for Linux on x86, but has since evolved to become a generic framework for creating dynamic analysis tools such as checkers and profilers. It is widely used by Linux programmers.
Vaporware – Vaporware (also spelt as vapourware) is software or hardware which is announced by a developer well in advance of its release, but which then fails to emerge, either with or without a protracted development cycle. The term implies deception, or at least a negligent degree of optimism; that is, it implies that the announcer knows that product development is in too early a stage to support responsible statements about its completion date, feature set, or even feasibility.
VB: Virtual Basic – Visual Basic (VB) is an event driven programming language and associated development environment prototyped by Alan Cooper as Project Ruby, then bought and vastly expanded by Microsoft. VB has been replaced by Visual Basic .NET. The older version of VB was derived heavily from BASIC and enables rapid application development (RAD) of graphical user interface (GUI) applications, access to databases using DAO, RDO, or ADO, and creation of ActiveX controls and objects.
Vbcc – Vbcc is a highly optimizing portable and retargetable ISO C compiler. It supports ISO C according to ISO/IEC 9899:1989 and a subset of the new standard ISO/IEC 9899:1999 (C99).
VBScript: Virtual Basic Script – The Visual Basic Script Edition (VBScript) is an Active Scripting language interpreted via Microsoft’s Windows Script Host. The language’s syntax reflects its pedigree as a variation of Microsoft’s Visual Basic programming language. It has gained significant support from Windows administrators seeking an automation tool more powerful than the batch language first developed in the late 1970s.

Veronica: Very Easy Rodent-Oriented Net-Wide Index to Computer Archives – Very Easy Rodent-Oriented Net-wide Index to Computer Archives (Veronica) is a search engine system for the Gopher protocol. Veronica is a constantly updated database of the names of almost every menu item on thousands of Gopher servers. The Veronica database can be searched from most major Gopher menus.
Vertical Software – Vertical software, also known as vertical application, is a king of software created for a specific kind of business or organization, such as hospitals or retail stores.
Video Game – A video game is a computer game where a video display such as a monitor or television is the primary feedback device.
Viewer Program – Viewer program is a utility software that enables you to read a file in its native format. Many shell utilities and file managers include viewers so that you can display different types of files.
VirtualGL: Virtual Graphics Library – VirtualGL, abbreviated from Virtual Graphics Library, is a program to remotely display a 3D application with hardware-accelerated rendering. VirtualGL non-intrusively converts any Unix/Linux OpenGL application into a thin client application, allowing for real-time interaction on a modest LAN regardless of data or geometry size.
Visual C++ – Visual C++, also known as MSVC, is an Integrated Development Environment (IDE) product for the C and C++ programming languages engineered by Microsoft. It has tools for developing and debugging C++ code, especially that written for the Microsoft Windows API, the DirectX API, and the Microsoft .NET Framework.
VisualKore – VisualKore is a modified version of the Ragnarok Online bot program known as Kore, originally made by Kura. The program is a derivative of OpenKore and henceforth has the same benefits of different and numerous contributors from all parts of the globe. VisualKore has intuitive graphical user interface as the main differential from OpenKore and other bots. VisualKore isn’t tolerated by official RO servers, but the software is fully legalized. Unlike most bots, VisualKore is a commercial program.
VMS: Virtual Memory System – Virtual Memory System(VMS) is the proprietary operating system originally produced by Digital Equipment Corp (DEC, now part of HP) for its VAX minicomputer. VMS V1 was released in August 1978. VMS was renamed “OpenVMS” around version 5.5. OpenVMS is a multi-user, multiprocessing virtual memory-based operating system (OS) designed for use in time sharing, batch processing, real time (process priorities can be set higher than OS kernel jobs) and transaction processing. It offers high system availability through clustering, or the ability to distribute the system over multiple physical machines. This allows the system to be “disaster-tolerant” against natural disasters that may disable individual data-processing facilities.
VRML: Virtual Reality Modeling Language – Virtual Reality Modeling Language (VRML) is a standard file format for representing 3-dimensional (3D) interactive vector graphics, designed particularly with the World Wide Web in mind. VRML, which functions as a counterpart to HTML, is a platform-independent language that creates a virtual reality scene which users can ‘walk’ through and follow links much like a conventional Web page. In some contexts, VRML can replace conventional computer interfaces with their icons, menus, files, and folders. It is possible to use VRML to create, for example, a virtual museum with all the elements of a real museum, including corridors, display cases and multimedia demonstrations.
