Glossary 207
capability
Refers to the actions that an object can perform, or actions that can be taken on
a managed object. For example, if a card is hot-pluggable, it is capable of being
replaced while the system power is turned ON.
CDRAM
Abbreviation for cached DRAM, which is a high-speed DRAM memory chip
developed by Mitsubishi that includes a small SRAM cache.
CD-ROM
Abbreviation for compact disc read-only memory. CD drives use optical
technology to read data from CDs. CDs are read-only storage devices; you cannot
write new data to a CD with standard CD drives.
certificate authority
A certificate authority is an industry-recognized entity. A certificate authority
verifies the identity of organizations requesting credentials to identify them to
other systems over networks or the Internet. Before issuing a certificate to an
applicant, the certificate authority requires proof of identity and other security
information.
chip
A set of microminiaturized, electronic circuits designed for use as processors and
memory in computers. Small chips can hold from a handful to tens of thousands
of transistors. They resemble tiny chips of aluminum, no more than 1/16" square
by 1/30" thick, which is where the term "chip" came from. Large chips, which can
be more than a half inch square, hold millions of transistors. It is actually only the
top one thousandth of an inch of a chip's surface that holds the circuits. The rest
of the chip is just a base.
CIM
Acronym for Common Information Model, which is a model for describing
management information from the DMTF. CIM is implementation independent,
allowing different management applications to collect the required data from a
variety of sources. CIM includes schemas for systems, networks, applications and
devices, and new schemas to be added. It provides mapping techniques for
interchange of CIM data with MIB data from simple network management
protocol (SNMP) agents and management information format (MIF) data from
DMI-compliant systems.
