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.
disk partition A logical section of a physical hard disk drive reserved for a specific file system
and function.
Distinguished Name
(DN) In the Lightweight Directory Access Protocol (LDAP), a unique text string that
identifies an entry’s name and location within the directory. A DN can be a
fully qualified domain name (FQDN) that includes the complete path from the
root of the tree.
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.
