Glossary of Terms
Boot ROM
An EPROM, that when installed on the System Board, allows the
PCWS to load its operating system, start-up files, and network files,
directly from image files located on a network sever running either
SCO-UNIX, or Windows NT. This allows the workstation to function in
a Client/Server environment such as 3700 RES without a hard disk.
On the Ultra System Board, the Boot ROM is not implemented as a
separate device. It is included in the System Flash BIOS chip and
enabled as needed through a Boot Menu. See Chapter 2 for more
information.
Buffer
An area of memory set aside to temporarily store data until it can be
processed, printed, or displayed.
Burst Cycles
Refers to the ability of the Pentium
sequential memory locations during read or write cycles. Burst cycles
are the fastest means of transferring data between the memory and
processor when the data or instructions are located at contiguous
memory addresses.
See Cache and Pipelining.
Bus
A set of electrical conductors used for communication between two or
more devices, a bus is a shared hiway that connects the CPU with
memory and peripheral devices.
Bus Mastering
A device that takes control of the ISA or PCI Bus in order to mediate
its own data transfers. The device that receives data from the bus
master is designated the bus slave or target. A process called bus
arbitration determines which device takes control of the bus.
Byte
A unit of data made up of eight contiguous bits. A byte is the smallest
unit of memory that can be addressed.
