equal to 8 bits.

Capacity –

The amount of information, measured in bytes, that can be

stored on a drive. Also known as

storage capacity

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

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.

GB –

(Gigabyte) Equal to 1,000,000,000 (billion) bytes.

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.

Hot-Swap –

This feature allows you to connect and disconnect external

devices while the computer and the devices are running. External drives,
such as the Maxtor OneTouch II drive can be hot-swapped.

KB –

(Kilobyte) Equal to 1,000 (thousand) bytes.

MB –

(Megabyte) Equal to 1,000,000 (million) bytes.
