memory. It stores the most recently used information (data,
instructions, etc.), and provides such information again to the
microprocessor more rapidly than could main memory.
See printed circuit board.
Central processing unit.
Customer-replaceable unit.
Direct memory access.
Dynamic random access memory.
DRAM single in-line memory module. A small printed circuit card
that contains dynamic random access memory (DRAM) chips.
External cache. Cache that is located external to the microprocessor.
See also cache.
A high-level programming language. A major feature of FORTH is
that user-defined operators can be used as if they were primitives.
An interactive command interpreter based on the FORTH
programming language. While in the Toolkit, you will see the ok
prompt. The Toolkit gives you access to an extensive set of functions
for performing fault isolation and debugging.
A printed circuit board installed in an SBus slot of the system unit
that controls a video display.
Field-replaceable unit.
Integrated circuit.
Identification.
Input/output. A device that inputs data to a computer CPU and
receives data from a computer CPU. Examples of I/O devices
include keyboards, mice, monitors, and peripherals devices.
Integer unit.
Local area network controller for Ethernet.
