-
AMLCD
-
An acronym for Active Matrix Liquid Crystal Display. A specific style of flat
panel display technology.
-
ASIC
-
An acronym for Application Specific Integrated Circuit. A silicon chip
designed to implement functions that would otherwise require several chips or
parts.
-
boot
-
To load the system software into memory and start it running.
-
boot PROM
-
In Sun workstations, contains the PROM monitor program, a command
interpreter used for booting, resetting, low-level configuration, and simple test
procedures.
-
DBRI
-
An acronym for Dual Basic Rate Interface. A Sun designed ASIC that
implements the hardware end of an ISDN interface.
-
default
-
A preset value that is assumed to be correct unless changed by the user.
-
Desktop Storage Module
-
An external data storage that contains a disk drive or a tape drive. Abbreviated
as DSM.
-
Desktop Storage Pack
-
An external data storage unit that contains a disk drive (Desktop Disk Pack), a
tape drive (Desktop Backup Pack), or a CD-ROM drive (Desktop SunCD Pack),
and that can be connected to a SPARCstation Voyager workstation.
Abbreviated as DSP.
-
Ethernet
-
A type of network hardware that allows communication between systems
connected directly together by transceiver taps, transceiver cables, and a
coaxial cable. Implemented in the SPARCstation Voyager workstation using
twisted-pair telecommunications wire and cable.
-
External Storage Module
-
An external unit that contains disk/tape drives and that can be connected to a
SPARCstation Voyager workstation. Abbreviated as ESM.
-
ISDN
-
An acronym for Integrated Services Digital Network. A technical standard that
provides for fully digital transmission and reception of data, and fully digital
end-to-end connectivity of telecommunications devices across a public
network.
-
Memory Card
-
A small board which usually contains several DRAMs. These cards are added
to a system to increase the amount of memory available to the CPU.
-
NVRAM
-
An acronym for non-volatile random access memory. The NVRAM is used to
store system variables used by the boot PROM. It also contains the system's
hostid number and Ethernet address.
-
PCMCIA
-
Personal Computer Memory Card International Association is an international
organization that has defined interface standards for Personal Computer
Cards. These PC Cards add memory, mass storage and I/O capabilities to
mobile computing systems. You can use a Sun modem contained on a PCMCIA
card on your SPARCstation Voyager workstation.
-
point-to-point protocol (PPP)
-
The successor to SLIP, PPP provides router-to-router and host-to-network
connections over both synchronous and asynchronous circuits.
-
power management
-
The regulation of a computer's power consumption.
-
Resume
-
Turning the power on after a suspend. The resume operation restores the
system to the point at which it was suspended.
-
SCSI Small Computer System Interface; pronounced "scuzzy."
-
SLAVIO
-
This chip contains all of the control logic referred to as slave I/O devices. These
devices are serial ports, floppy controller, EPROM, TOD chip and NVRAM.
-
suspend
-
A means of turning off the power in which the system state is saved to disk.
See also resume.
-
system
-
Any computer that allows you to run programs or applications. In this book, it
means the SPARCstation Voyager workstation unit together with the Sun
operating system and peripheral hardware devices.
-
system unit
-
The enclosure containing the system memory, central processing unit, hard
disk, floppy drive, and video board.
-
TOD
-
An acronym of Time of Day. This is a special timekeeping chip that keeps track
of what day and time it is.
