PCIPeripheral pc DevicesA 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.
A way to verify the accuracy of data transmitted over the SCSI bus. The parity bit in the transfer is used to make the sum of all the 1 bits either odd or even (for odd or even parity). If the sum is not correct, the information may be retransmitted or an error message may appear.
The electrical connection required at each end of the SCSI bus, composed of a set of resistors. It improves the integrity of bus signals.
Peripheral Component Interconnect. A local bus specification that allows connection of peripherals directly to computer memory. It bypasses the slower ISA and EISA buses.
A piece of hardware (such as a video monitor, disk drive, printer, or
The alignment of pin 1 on a SCSI cable connector and the
Programmed Input/Output. A way the CPU can transfer data to and from memory using the computer’s I/O ports. PIO is usually faster than DMA, but requires CPU time.
Port Address Also Port Number. The address through which commands are sent to a host adapter board. This address is assigned by the PCI bus.

Queue Tags A way to keep track of multiple commands that allow for increased throughput on the SCSI bus.
