Glossary

An application that runs on top of the network operating system. VAPs tie in with the network operating system so that print servers, archive servers, and database servers can provide services without interfering with the network's normal operation. VAPs run on top of the operating system in much the same way a word processing or spreadsheet application runs on top of DOS. NLM programs provide this type of enhancement for NetWare.

A code for assigning a value from the whiteboard to a property in a condition or action. In the Rule Editor, if a condition or action property has a caret (^) as part of its name, you can use the special code valueOf.whiteboardkey, where whiteboardkey is the name of the key whose value you want. When your application fires the rule, it substitutes the key's value for the special code. Several Rule Editor constants, such as userID and today, can be used like whiteboard keys in valueOf! expressions.

A file format for the exchange of contact information. When you get an address card attached to an e-mail, it's probably in vCard format. Contrast with search folder.

1. Video Display Terminal: computer monitor; an input/output device with a display screen and an input keyboard.2. Video Dial Tone: A type of network that carries TV over telephone lines.3. Volume Definition Table: A table that keeps track of volume segment information such as volume name, volume size, and where volume segments are located on various network hard disks. Each NetWare volume contains a volume definition table in its NetWare partition.

Video Electronic Standards AssociationA consortium of manufacturers formed to establish and maintain industry-wide standards for video cards and monitors. VESA was instrumental in the introduction of the Super VGA and Extended VGA video graphics standards with a refresh rate of 70 Hz, minimizing flicker and helping to reduce user eyestrain and fatigue.

virtual file allocation tableA scheme to access filesystems using a 32-bit protected mode filesystem driver outside the DOS kernel. VFAT uses direct BIOS or hardware access to disk and integrated caching to make access faster.

A circuit board that enables a computer to display information on its screen. The resolution, number of colors, and refresh rate of a monitor is determined by the kind of video card used, plus the limitations of the monitor itself. Also called graphics adapter, display adapter, video adapter.

A type of network that carries TV over telephone lines.

Computer monitor; an input/output device with a display screen and an input keyboard.

In ZENworks Server Management, a mechanism through which you can create a view to display information from the agents that have instrumented SNMP MIBs and traps sent by the agent to the management site server.

In NetWare Administrator, the set of toolbar buttons that are unique to the active tool. They are inserted in the position marked by [Active View Buttons] on the Toolbar - Main Features tab.

In ZENworks Server Management, a representation of the managed server or workstation desktop. It is displayed on the management console when the remote operator initiates a Remote Management session.

A type of circuit that provides a connection-oriented service similar to that of circuit switching, but with the following exceptions:

• It is limited to a connection between two end points.
• It has the advantage of economical statistical multiplexing for establishing a logical path through the network.

This logical path can be provided either on a permanent basis by a permanent virtual circuit (PVC), which is equivalent to a leased circuit, or on a request basis by an switched virtual circuit (SVC). Once the logical path is established, the packets are transferred between connected ends, as desired.

A method that determines which packets belong to a virtual circuit. Each packet can contain a 4-bit logical group number and an 8-bit logical channel number.

Provides multiple "screens" on which a user can log in and run programs. One screen is displayed on the computer's monitor at any given time; a key sequence is used to switch between virtual consoles.

An Internet discussion group that presents the results of a search across multiple discussion groups in order to enable easy access to a specific topic.

A scheme to access filesystems using a 32-bit protected mode filesystem driver outside the DOS kernel. VFAT uses direct BIOS or hardware access to disk and integrated caching to make access faster.

In the Novell Web Server environment, a logical entity within a virtual server that acts as a Web Server, with its own DNS hostname or IP address. A virtual host has its own document and log files, but it uses the virtual servers configuration files.

The software that extends a network backbone area by linking two partitioned areas.

An executable program for a DOS workstation used to enable various kinds of communications with a server, or to enable applications on a server running NetWare 4 or an earlier version. For example, the NetWare DOS Requester is a suite of VLM programs, as is Desktop SNMP.

A memory management scheme that permits execution of programs larger than the size of physical memory. Using virtual memory, least-used data is moved out of memory to disk, thus freeing memory for other uses. When the data is needed again, it is returned to memory where it is swapped for other data that is then moved to disk.

A data network that uses the public telecommunications infrastructure, but maintains privacy through the use of a tunneling protocol and security procedures. A VPN gives a company the same capabilities as a system of owned or leased lines to which that company has exclusive access. However, costs are much lower because the VPN uses the shared public infrastructure rather than exclusive line access.

A collection of one or more indexes and related configuration files characterized by a unique name (for example, search.digitalairlines.com). A virtual search server is the NetWare Web Search method of creating and hosting a search service intended for a specific audience and purpose.

The person who has administrative control over one or more virtual search servers.

In ZENworks Desktop Management and ZENworks Server Management, a logical server, rather than a physical node, to which cluster-enabled shared volumes are tied.

An IBM-licensed program composed of loadable modules that control telecommunications by identifying communications resources to the host operating system (System/370).

A program that inserts itself into other files or programs. When executed, it spreads to more programs and other computers. A virus can cause substantial damage by clogging networks or disk drives, deleting files, or opening security holes.

Virtual LANA local area network with a definition that maps workstations on some basis other than geographic location. For example, by department, type of user, or primary application.

Virtual Loadable ModuleAn executable program for a DOS workstation used to enable various kinds of communications with a server, or to enable applications on a server running NetWare 4 or an earlier version. For example, the NetWare DOS Requester is a suite of VLM programs, as is Desktop SNMP.

The NetWare volume error log.

In ZENworks Desktop Management, part of the Windows Group Policy. The volatile setting indicates that the original local Group policy settings will be restored when the user logs out (user settings are restored) or when the system shuts down (workstation settings are restored).

In Novell Storage Services (NSS), an option in the Administration menu that allows NSS partitions and storage groups, when they are created, to be subdivided into NSS volumes.

A table that keeps track of volume segment information such as name, size, and location on various network hard disks. Each NetWare volume contains a Volume Definition table in its NetWare partition.

On the desktop, an icon that looks like a filing cabinet. In the Browser, an icon that resembles a hard disk. Each icon represents a volume on the server.

A leaf object in the Novell Directory Services (NDS) tree that represents a physical volume on the network. Its properties can store information about its location, owner, space use restrictions, statistical information, and so forth.

A physical division of a volume. A volume can span up to 32 disk drives. If a volume includes more than one drive, each drive in the volume is a volume segment.

virtual private networkA data network that uses the public telecommunications infrastructure, but maintains privacy through the use of a tunneling protocol and security procedures. A VPN gives a company the same capabilities as a system of owned or leased lines to which that company has exclusive access. However, costs are much lower because the VPN uses the shared public infrastructure rather than exclusive line access.

Virtual Telecommunications Access MethodAn IBM-licensed program composed of loadable modules that control telecommunications by identifying communications resources to the host operating system (System/370).
