SCSI controller
SCSI interface
(Or "host adapter") A device that communicates
between a computer and its SCSI peripherals. The SCSI
adapter is usually assigned SCSI ID 7. It is often a
separate card that is connected to the computer's bus
(e.g. PCI, ISA, PCMCIA) though increasinly, SCSI
adapters are built in to the motherboard. Apart from being
cheaper, busses like PCI are too slow to keep up with the
newer SCSI standards like Ultra SCSI and Ultra-Wide SCSI.
There are several varieties of SCSI (and their connectors) and
an adapter will not support them all.
The performance of SCSI devices is limited by the speed of the
SCSI adapter and its connection to the computer. An adapter
that plugs into a parallel port is unlikely to be as fast as
one incorporated into a motherboard. Fast adapters use DMA
or bus mastering.
Some SCSI adapters include a BIOS to allow PCs to boot
from a SCSI hard disk, if their own BIOS supports it.
Adaptec make the majority of SCSI chipsets and many of the
best-selling adapters.
Note that it is not a "SCSI controller" - it does not control
the devices, and "SCSI interface" is redundant - the "I" of
"SCSI" stands for "interface".
