Glossary of Terms and Abbreviations
B-3
File
A named collection of information stored on a disk.
Firmware
Software that is permanently stored in ROM. Therefore, it can be
accessed during boot time.
Hard Disk
A disk made of metal and permanently sealed into a drive cartridge. A
hard disk can store very large amounts of information.
Host
The computer system in which a SCSI host adapter is installed. It uses
the SCSI host adapter to transfer information to and from devices
attached to the SCSI bus.
Host Adapter
A circuit board or integrated circuit that provides a SCSI bus connection
to the computer system.
Internal SCSI
Device
A SCSI device installed inside the computer cabinet. These devices are
connected in a continuous chain using an unshielded ribbon cable.
IRQ
Interrupt Request Channel. A path through which a device can get the
immediate attention of the computer’s CPU. The PCI bus assigns an IRQ
path for each SCSI host adapter.
ISA
Industry Standard Architecture. A type of computer bus used in most
PCs. It allows devices to send and receive data up to 16-bits at a time.
Kbyte
Kilobyte. A measure of computer storage equal to 1024 bytes.
Local Bus
A way to connect peripherals directly to computer memory. It bypasses
the slower ISA and EISA buses. PCI is a local bus standard.
Logical Unit
A subdivision, either logical or physical, of a SCSI device (actually the
place for the device on the SCSI bus). Most devices have only one logical
unit, but up to eight are allowed for each of the eight possible devices on
a SCSI bus.
LUN
Logical Unit Number. An identifier, zero to seven, for a logical unit.
Mainboard
A large circuit board that holds RAM, ROM, the microprocessor, custom
integrated circuits, and other components that make a computer work. It
also has expansion slots for host adapters and other expansion boards.
Main Memory
The part of a computer’s memory which is directly accessible by the CPU
(usually synonymous with RAM).
Mbyte
Megabyte. A measure of computer storage equal to 1024 kilobytes.
