Glossary

The central layer of the Novell Storage Services (NSS) Media Access Layer (MAL). The object bank is responsible for registration of storage managers and storage data objects. Storage free space is recognized by NSS and deposited into the object bank for NSS use.

The structure that the network administrator chooses and provides with data in order to create a Novell Directory Services (NDS) object. The types of object classes are the same as the names of the objects themselves. For example, User, Organization, Server, etc.

Short for "object engine layer."

In Novell Storage Services (NSS), a layer in the software architecture that stores and manages NSS objects such as files and NSS volumes.

A property that identifies categories of information associated with an object.

A component in the CORBA programming model that acts as the middleware between clients and servers. In the CORBA object-based computing model, a client can request a service without knowing anything about which servers are attached to the network. The various ORBs receive the requests, forward them to the appropriate servers, and then hand the results back to the client. Novell has its own ORB.

Any of the rights needed to access an object. The object that possesses the rights is called the trustee. With the exception of the Supervisor object right, object rights do not affect properties or property rights. However, the Supervisor object right grants access to all property values.

Short for "Object Trustees property."

A secret token, such as a password or fingerprint, that authenticates (uniquely identifies) a user to the system.

Original Equipment ManufacturerA company that manufactures computer equipment which it then sells to other computer makers and vendors who, in turn, sell it to end users.

offline uninterruptible power sourceA backup power unit that supplies uninterrupted power if a commercial power outage occurs. Offline UPS monitors the power line. When power drops, the UPS is activated. The drawback to this method is the slight lag before the offline UPS becomes active. However, most offline UPS systems are fast enough to offset this lag.

The number of subdirectories and files in a directory.

A location option while installing the NetWare Connect Service Client in the workstation. It defines a profile for situations when you are not connected to the network. (Context: "Includes dial up access to the network to allow you to be more productive at home and on the road, saving you time".)

A type of call that is activated by the presence of data traffic directed to or through the remote peer system.

A method of connecting to a remote system that enables occasional instead of permanent access, thereby saving connection expense and maximizing the use of network resources. This type of connection uses static routing information to advertise the presence of exterior networks, although no route currently exists.

on-demand switched virtual circuitA virtual circuit that is closed after data has been transmitted over the established switched virtual circuit (SVC). The circuit remains closed until more data is queued for sending, at which point connection is reestablished.

on-demand SVCA virtual circuit that is closed after data has been transmitted over the established switched virtual circuit (SVC). The circuit remains closed until more data is queued for sending, at which point connection is reestablished.

1. An electronic documentation file formatted according to the requirements of the destination operating system. Help files generally contain short instructions about how to perform certain features. They generally have fewer graphics than printed or electronic books of the same material. Help files reformat as needed to the screen window dimensions, and make heavy use of hypertext linking, pop-up boxes, and so forth. Help files are context-sensitive, which means that you can jump to a specific topic within the help file directly from the applications dialog and menu interface, etc.

The interface used on NetWare servers to support multiple network boards as well as multiple protocol stacks, such as TCP/IP, IPX/SPX, or AppleTalk.

When a file is opened or created, an internal data structure called an Open File Structure is allocated that represents that state of that open file. The user gets back a key to the open file structure that must be used for all subsequent accesses to the file (reads, writes, wild-reads, and getting and modifying file metadata).

A license used for creating free and open publications; created by the Open Content Project. The license is generally focused at academics; however, some artists have found it suitable to their tastes.

A set of computer programs providing encrypted communication sessions over a computer network. It was created as an open alternative to Secure Shell (SSH).

A hierarchical Interior Gateway Protocol routing algorithm that relies on OSPF routers having constructed a complete topology of the network from link states. For each destination, the router examines its link state database and selects the shortest path as the route to that destination. OSPF then allows the routers to derive such information as least-cost routing, equal-cost routing, and load balancing.

A program in which the source code is available to the general public for use and/or modification from its original design free of charge, ie, open. Open source code is typically created as a collaborative effort in which programmers improve upon the code and share the changes within the community.

Short for "Open Systems Interconnection model."

OSI modelA seven-layer model for data communication which is the standard network architecture developed by the International Organization for Standardization (ISO). The layers are as follows: physical, data-link, network, transport, session, presentation, and application.

A free, open source implementation of the Lightweight Directory Access Protocol (LDAP). It is released under its own OpenLDAP license. It has been included with several common Linux distributions.

Open Secure Shell A set of computer programs providing encrypted communication sessions over a computer network. It was created as an open alternative to Secure Shell (SSH).

The master control program that runs the computer. It is the first program loaded when the computer is turned on, and its main part, called the kernel, resides in memory at all times. The operating system performs basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. The operating system acts as an interface between the user and the computer, enabling the user to operate software applications and access all resources available on the computer, including the CPU, media drives, memory, printers, and storage devices.

A high-capacity storage device, sometimes called a jukebox, that uses an autochanger mechanism to mount and dismount optical discs as needed.

A mandatory container object in the Novell Directory Services (NDS) tree that represents an organization such as a corporation, university, or operating division. It contains the objects that represent the network users and resources in the actual organization. It must reside either immediately under the root of the tree or under a Country object.

Organizational Certificate AuthorityA certificate authority (CA) that a network administrator creates using ConsoleOne. The Organizational CA is specific to the organization and uses a private key for signing operations.

Short for "Organizational Role object."

A leaf object in the Novell Directory Services (NDS) tree that represents a position or role, such as Team Leader or Accounting Resources Manager, that can be filled by any designated user. Using it simplifies rights management, because an administrator grants rights to the Organizational Role object. The designated user who fills that role then has those rights.

Short for "Organizational Unit object."

OU objectAn optional container object in a Novell Directory Services (NDS) tree that represents a unit within an organization, such as a department or business unit. It contains the objects that represent the network users and resources in the actual unit. It must reside either immediately under an Organization object or under another Organizational Unit.
