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 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 the computer processor’s data path. 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. Most devices have only one logical unit, but up to sixteen are allowed for a 16-bit SCSI bus and eight for an 8-bit SCSI bus.

LUN (logical unit number) An encoded three-bit number for the logical unit.

LVD (low-voltage differential)

A robust design methodology that improves power consumption, data integrity, cable lengths, and support for multiple devices while providing a migration path for increased I/O performance.

MByte (megabyte) A measure of computer storage equal to 1024 kilobytes.

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 plug-in boards.

main memory The part of a computer’s memory that is directly accessible by the CPU (usually synonymous with RAM).

motherboard See mainboard. In some countries, the term motherboard is not appropriate.

multi-taskingThe initiation and control of more than one sequence of operations. This allows programs to operate in parallel.

multi-threadingThe simultaneous accessing of data by more than one SCSI device. This increases the aggregate data throughput.

NVRAM (Non-Volatile Random Access Memory) An EEPROM (Electronically Erasable Read Only Memory chip) used to store configuration information.

operating system A program that organizes the internal activities of the computer and its peripheral devices. An operating system performs basic tasks such as moving data to and from devices, and managing information in memory. It also provides the user interface.
