Digital Signature

Algorithm (DSA) A cryptographic algorithm specified by the Digital Signature Standard (DSS). DSA is a standard algorithm used to create digital signatures.

direct memory access

(DMA) The transfer of data directly into memory without supervision of the processor.

directory server In the Lightweight Directory Access Protocol (LDAP), a server that stores and provides information about people and resources within an organization from a logically centralized location.

disk array A storage subsystem containing an arrangement of multiple disk drives, designed to provide performance, high availability, serviceability, and other benefits.

Distributed

Management Task Force

(DMTF) A consortium of over 200 companies that authors and promotes standards for the purpose of furthering the ability to remotely manage computer systems. Specifications from the DTMF include the Desktop Management Interface (DMI), the Common Information Model (CIM), and the Alert Standard Format (ASF).

domain A grouping of hosts that is identified by a name. The hosts usually belong to the same Internet Protocol (IP) network address. The domain also refers to the last part of a fully qualified domain name (FQDN) that identifies the company or organization that owns the domain. For example, “sun.com” identifies Sun Microsystems as the owner of the domain in the FQDN “docs.sun.com.”

domain name The unique name assigned to a system or group of systems on the Internet. The host names of all the systems in the group have the same domain name suffix, such as “sun.com.” Domain names are interpreted from right to left. For example, “sun.com” is both the domain name of Sun Microsystems, and a subdomain of the top-level “.com” domain.

domain name server

(DNS) The server that typically manages host names in a domain. DNS servers translate host names, such as “www.example.com,” into Internet Protocol (IP) addresses, such as “030.120.000.168.”

domain name service

(DNS) The data query service that searches domains until a specified host name is found.
