A-19

CPU (Central Processing Unit)

The CPU, sometimes called “Processor,” actually functions as the “brain” of the computer. It inter-

prets and executes program commands and processes data stored in memory.

Device Driver

A device driver is a special set of instructions that allows the computer’s operating system to commu-

nicate with devices such as VGA, audio, Ethernet, printer, or modem.

DVD

DVD is essentially a bigger, faster CD that can hold video as well as audio and computer data. With these

capacities and access rates, DVD discs can provide you with dramatically-enhanced high-color, full-mo-

tion videos, better graphics, sharper pictures, and digital audio for a theater-like experience. DVD aims to

encompass home entertainment, computers, and business information with a single digital format, eventually

replacing audio CD, videotape, laserdisc, CD-ROM, and video game cartridges.

ExpressCard

ExpressCard slot is 26 pins and support one ExpressCard/34mm or one ExpressCard/54mm expansion

card. This new interface is faster by using a serial bus supporting USB 2.0 and PCI Express instead of

the slower parallel bus used in the PC card slot. (Not compatible with previous PCMCIA cards.)

Hardware

Hardware is a general term referring to the physical components of a computer system, including

peripherals such as printers, modems, and pointing devices.

IDE (Integrated Drive Electronics)

IDE devices integrate the drive control circuitry directly on the drive itself, eliminating the need for a

separate adapter card (in the case for SCSI devices). UltraDMA/66 or 100 IDE devices can achieve up

to 33MB/Sec transfer.

IEEE1394 (1394)

Also known as iLINK (Sony) or FireWire (Apple). 1394 is a high speed serial bus like SCSI but has simple

connections and hot-plugging capabilities like USB. The popular 1394a interface has a bandwidth of

400Mbits/sec and can handle up to 63 units on the same bus. The newer 1394b interface can support twice

the speed and will appear in future models when peripherals support higher speeds. 1394 is also used in

high-end digital equipment and should be marked “DV” for Digital Video port.

Kensington

Locks

Kensington

locks (or compatible) allow the Notebook PC to be secured usually using a metal cable

and lock that prevent the Notebook PC to be removed from a xed object. Some security products

may also include a motion detector to sound an alarm when moved.
