A collection of unbroken signal lines across which information is
transmitted from one part of a computer system to another. Connections
to the bus are made using taps or connectors on the lines.
A high-performance way to transfer data. The host adapter controls the
transfer of data directly to and from system memory without bothering
the computer's microprocessor. This is the fastest way for multitasking
operating systems to transfer data.
A unit of information consisting of eight bits.
In computers, the linking together of two or more SCSI devices so that
they are dependent upon one another for operation.
A set of SCSI devices connected in a series. When devices are
daisy-chained to a microcomputer, the first device is connected to the
computer, the second device is connected to the first, and so on down
the line.
A program that allows a microprocessor (through the operating system)
to direct the operation of a peripheral device.
A SCSI device installed outside the computer cabinet. These devices are
connected in a continuous chain using specific types of shielded cables.

A named collection of information stored on a disk.
A disk made of metal and permanently sealed into a drive cartridge. A
hard disk can store very large amounts of information.
