(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 XP 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.
Network
A group of computers and devices, such as printers
and scanners, connected by a communications link.
A network can be either small or large and can be
connected permanently through cables or temporarily
through telephone lines or wireless links. The biggest

before the monitor or hard drive turns off. The settings
are saved as a power scheme.
