Glossary of Terms
Checksum
An error checking mechanism for a range of data. The sum of a data
block is compared with the sum of another data block. The carry is
ignored. A discrepancy indicates an error.
Chip
An Integrated Circuit.
Chipset
One or more integrated circuits that when combined, comprise all of
the original support circuitry of the IBM AT PC. The original
implementation included a clock generator, bus controller, memory/
cache controller, real time clock, counter/timers, interrupt controller,
and DMA controller. In addition, modern chips sets add DRAM, cache,
PCI-to-ISA host controllers and power management features.
The PCWS Ultra System Board uses a Silicon Integrated Systems
Corp. SiS5581.
Client
A workstation or personal computer that requests services from a
server over a network. The server is usually a high speed
microcomputer, minicomputer, or mainframe, providing access to a
database. The client provides the user interface and may perform some
or all of the application processing.
CMOS
Abbreviation for Complementary Metal Oxide Semiconductor. A
method of fabricating integrated circuits. CMOS RAM chips typically
consume very little energy which allows a battery to maintain the
contents.
CMOS RAM
A small amount of memory located in every IBM AT Compatible PC
that stores system configuration information. Information is stored or
retrieved from the CMOS RAM by the system BIOS Setup Utility. The
CMOS RAM is backed-up with a battery to preserve the contents when
the system is turned off.
