The Glossary lists the terminologies used in this User Guide. For terminologies other than these, look in Windows Help.
DDR SDRAM  
(Double Data Rate Synchronous Dynamic Random Access Memory)
DRAM is a memory type whose cells consist of a capacitor and 
transistor manufactured at a low price. SDRAM is a memory type 
whose performance has been improved by synchronizing the clock 
with the external CPU clock. DDR SDRAM is a memory type whose 
performance has been improved by doubling the operating speed 
of the SDRAM and is widely used nowadays. This computer uses 
DDR SDRAM.
DHCP (Dynamic Host Configuration Protocol)
This refers to automatically allocating IP addresses to the users on 
the network by the network administrators.
Firewall
A security system used to protect an internal network or intranet 
from external networks through an authentication procedure.
HDMI
This is a digital video / audio interface specification that transmits 
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.
