Glossary-5
D
Data Encryption
Standard (DES) A common algorithm for encrypting and decrypting data.
Desktop Management
Interface (DMI) A specification that sets standards for accessing technical support information
about computer hardware and software. DMI is hardware and operating
system (OS) independent, and can manage workstations, servers, or other
computing systems. DMI is defined by the Distributed Management Task Force
(DMTF).
digital signature A certification of the source of digital data. A digital signature is a number
derived from a public key cryptographic process. If the data is modified after
the signature was created, the signature becomes invalid. For this reason, a
digital signature can ensure data integrity and detection of data modification.
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 which 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).
