API Application Programming Interface. ASIC Application Specific Integrated Circuit. attribute A piece of information about a component; the building block of the Management Information Format (MIF). An attribute describes a single characteristic of a manageable product or component. For example, the clock speed of a processor chip is an attribute of a group that describes that chip. A set of related attributes constitutes a group. CI Component Interface; the Desktop Management Interface layer used by component instrumentation. CLSID A class ID; a form of a UUID (GUID). COM Component Object Model. Common Information Model (CIM) An object-oriented schema that is being defined by a subcommittee of the DMTF. CIM will serve as the management information schema for WBEM, along with other specifications to be defined. CIM is designed to be extended for each operating environment in which it is used. For CIM specifications, see http://www.dmtf.org/work/cim.html. component Any hardware, software or firmware element contained in a computer system. For example, a modem, printer, network interface card, spreadsheet software program and the operating system could all be considered components. component instrumentation The executable code that provides DMI management functionality (attribute values, etc.) for a particular component. component interface (CI) The Desktop Management Interface layer used by component instrumentation. DDK Device Driver Kit. debug Mobile CI Code compiled into the Mobile CI Manager that allows the OEM to view Mobile CI messages and data by using the MT_Mobile CI. Desktop Management Interface (DMI) A platform management information framework built by the Desktop Management Task Force, Inc. (DMTF), designed to provide manageability for desktop and server computing platforms by providing an interface that is: Independent of any specific desktop operating system, network operating system, network protocol, management protocol, processor or hardware platform. Easy for vendors to implement. Easily mapped to higher-level protocols. For DMI specifications see http://www.dmtf.org/tech/specs.html. device change detection A module of the Mobile CI Manager layer that provides an interface into the Windows* Plug and Play system, allowing the Mobile CI to receive and react to dynamic changes in the system configuration. DHCP Dynamic Host Configuration Protocol, one of the IETF standard protocols. For new system setup, the Client broadcasts a DHCP request containing an extension identifying the remote new system setup protocol. Assuming the Server recognizes the request, it sends the Client an executable file. The Client uses TFTP to download the executable, then executes the image (such as an OS). direct interface instrumentation A program that runs in the background and maintains an entry point to the Service Provider at all times. The Service Provider communicates directly with it to perform various DMI command functions. DLL Dynamic Linked Library. DMI compliance The DMTF owns the responsibility for defining the definition of DMI 2.0 compliance. For further information, contact http://www.dmtf.org. DMI Component Test System (DCTS) A Windows-based development tool for exercising test component instrumentation. DMI to SNMP Mapper Tool that facilitates writing a standard SNMP-based management application which can manage the functionality defined by a set of standard DMTF MIF groups, independent both of the component that implements those groups and of the system on which that component is installed. The Mapper also provides SNMP access to any component MIF installed on a DMI-instrumented system. Intel offers DMI to SNMP Mappers for Microsoft Win32* and Novell NetWare*. DMI Service Provider (DMI SP) An application that runs on the target system and provides services between the management application (MA) and component instrumentation. The DMI SP arbitrates access to component instrumentation and manages the Management Information Format (MIF) database. DMI SP interface The interface that manages all communications with the DMI SP. DMI-enabled A product is DMI-enabled if it interoperates with other DMI-enabled products according to the DMI Specification Version 2.0 and the DMI 2.0 Conformance Guidelines published by the DMTF (available at: http://www.dmtf.org/tech/specs.html) DMTF The DMTF brings together leading companies from all areas of the computer industry to create the standards and infrastructure for cost-effective management of PC systems. Members of the DMTF benefit from front-line access to information about DMTF standards, the opportunity to participate in the process of defining these standards and the synergy of working with other vendors who are addressing similar implementation issues. Companies that fit any one of the following descriptions should consider joining the more than 100 vendors who are already active members of the DMTF: Providers of any type of PC product or peripheral—application software, management software, servers, desktop systems, printers, modems, sound cards, network adapters, etc. Vendors interested in developing a standard management framework for their products and services. Vendors interested in using DMI to differentiate and add value to products and services. Vendors with customers that request or require standards-based management solutions. enumeration One list of possible values for a given attribute, declared either globally or locally. Global enumeration values are used by other attributes within a component; local enumeration values are used by only a single attribute. event Unsolicited information sent from a component to the Service Provider detailing an unusual circumstance or notable event. This information is then sent by the Service Provider to all management applications registered for event notification. For example, events can be sent when an error occurs or when a new version of a piece of software is installed. Component manufacturers determine which events will be related to their product and what information will be passed about the event.
