Visual Basic for Applications (VBA) is the version of Microsoft’s Visual Basic (VB) used to create basic and customized programs.
Industry:Technology
Visual Basic Extension (VBX) is a Visual Basic add-on that Microsoft is converting to an Object Linking and Embedding (OLE) Custom Controls (OCX) infrastructure.
Industry:Technology
Visual Basic (VB) is a high-level programming language from Microsoft.

A visitor location register (VLR) is a server in a cellular network that supports roaming functions for users outside the coverage area of their own HLR. The VLR uses Signaling System 7 to obtain information about the user from the HLR, and then establishes a temporary record on the VLR while the user is within the VLR coverage area, ensuring mobility management and call-handling functions.

The virtualization software market includes all software products that are sold as value-added options to run on an x86 server or a desktop to create or manage a specific virtualized environment. Revenue is for new license sales and for maintenance and support services that include new version license sales to update an existing license to a new version, telephone support and on-site remedial support. Revenue does not include professional services. For products to be included in this coverage, they must represent a revenue stream for the company that is separately tracked and not be only part of a bundled product or service. The virtualization software market is divided into three segments: server virtualization infrastructure, server virtualization management and HVDs. Other forms of virtualization software, such as application virtualization, shared OS virtualization, mainframe virtualization and thin provisioning, are not included in specific virtualization revenue reporting at this time.
Industry:Technology
Virtualization is the abstraction of IT resources that masks the physical nature and boundaries of those resources from resource users. An IT resource can be a server, a client, storage, networks, applications or OSs. Essentially, any IT building block can potentially be abstracted from resource users.
Industry:Technology
A virtual tape library (VTL) is a disk appliance that has special software that makes the device appear as a physical tape drive or tape library to the backup application; the device is accessed through standard tape interfaces. The backup software believes it is writing the backup data to a real tape cartridge when it is, in fact, writing to a specially configured file on the disk appliance. Similarly, the backup software will use the appliance for recovery, accessing the device as if the recovery is coming from tape, when it is actually being transferred from disk spindles on the appliance. At its essence, a VTL is both a disk-based appliance and a tape-like interface.
Industry:Technology
A virtual switch provides three primary capabilities for communications within a virtualized environment: switching, security controls and visibility. A virtual switch provides connectivity among instances within the virtual environment, without the communication having to go through the standard physical switches connected to the virtualized servers.
Industry:Technology
A virtual server facility (VSF) is a feature of second-generation Advanced CMOS-ECL (ACE) technology that effectively allows a user to physically partition a system into multiple systems, all within the cabinetry of the bigger system.
Industry:Technology
Virtual Reality Modeling Language (VRML) provides a means of rendering 3D worlds from mathematical equations or descriptions. A VRML browser can create shapes and text within a navigable 3D context. The v.2.0 specifications further enhance the immersive experience, allowing for such real-world events as interaction between “visitors” and collision detection when a user “bumps into” an object or other users.
