Glossary 737
chip
A set of microminiaturized, electronic circuits that are designed for use as
processors and memory in computers. Small chips can hold from a handful to
tens of thousands of transistors. They look like 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 it 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 will be added. It provides mapping techniques for
interchange of CIM data with MIB data from SNMP agents and MIF data from
DMI-compliant systems.
CIMOM
Acronym for common information model object manager.
CI/O
Acronym for comprehensive input/output.
CMOS
Acronym for complementary metal-oxide semiconductor. In computers,
CMOS memory chips are often used for NVRAM storage.
COM n
The device names for the first through fourth serial ports on your computer are
COM1, COM2, COM3, and COM4. The default interrupt for COM1 and COM3
is IRQ4, and the default interrupt for COM2 and COM4 is IRQ3. Therefore, you
must be careful when configuring software that runs a serial device so that you
don’t create an interrupt conflict.
component
As they relate to DMI, manageable components are operating systems, computer
systems, expansion cards, or peripherals that are compatible with DMI. Each
component is made up of groups and attributes that are defined as relevant to
that component.
