Daisy chain –
A hardware configuration in which peripheral
devices are connected to each other in a series. The FireWire
interface, for example, supports a daisy chain of up to 62
drives.
Data Transfer Rate –
The speed at which data transfers to
and from the drive.
Defrag – (or defragment) A software utility that keeps the data
for each file physically contiguous on the drive, which can
enhance your drive’s performance.
Device Driver – A software program that enables a PC to
communicate with peripheral devices such as hard drives and
CD-ROM drives. Each type of device requires a different
driver. Device driver programs are stored on a computer’s hard
drive and are loaded into memory when the computer is
started or when a device is plugged into the computer.
External Hard Drive –

Me operating systems used to partition a hard drive.
FireWire –
The FireWire interface, also known as 1394 and
i.LINK, is a high-performance, serial bus defined by the
Institute of Electrical and Electronics Engineers (IEEE) as a
standard for connecting digital devices together. It is ideal for
connecting computers and hard drives to digital video and
audio equipment.
Format –
Formatting erases all information on a hard drive
and sets up the file system for storing and retrieving files. On
Macintosh systems, high-level formatting is often referred to as
initialization. Low-level formatting sets up the locations of
sectors on the drive. Your drive was formatted with the FAT32
file system at the factory.
GB – (Gigabyte) Equal to 1,000,000,000 (billion) bytes. For a
detailed explanation, refer to page 29.
Hard Drive –
An electromechanical device used for
information storage and retrieval, incorporating one or more
rotating disks on which data is recorded, stored, and read
magnetically.
