DVD (Digital Versatile Disk)

DVD was developed to replace CD

(compact disk). Although the shape and 

size of the disc are the same as that of

a CD, the capacity of a DVD is at least

4.7GB while the capacity of a CD is 

600MB. DVD video is digital unlike VHS 

(analog) video and supports MPEG

compression and digital audio. To play a 

DVD, a DVD drive is required.

A security system used to protect an

internal network or intranet from external

networks through an authentication

procedure.

A power mode that saves all data in

memory to the hard disk and turns the

CPU and hard disk off. When canceling 

Hibernation Mode, all application

programs that were running are restored

to their last state.

This refers to a small image that

represents a file that users can use.

LAN (Local Area Network)

A communications network connecting

computers, printers and other devices

within a local area such as within a

building. A LAN enables all connected 

devices to interact with other devices

on the network. The current LAN uses 

the Ethernet media access control

method developed in the early 1980s. 

To connect to an Ethernet, a network

card called a LAN card, Ethernet card

or network interface card is required. 

To exchange data between computers,

a protocol is required besides the

hardware equipment. Windows Vista 

uses TCP/IP as the default protocol.

LCD (Liquid Crystal Display)

There are Passive Matrix and Active

Matrix LCD types. This computer uses 

the Active Matrix type LCD called a TFT

LCD. Since an LCD is implemented by 

transistors instead of a cathode-ray tube

unlike a CRT, its size can be slim. And 

because it does not blink, it reduces eye

strain.
