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 MPEG2

compression and digital audio. To play a DVD, a DVD drive is

required.

from external networks through an authentication procedure.

video and audio signals over a single cable.

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.
