Ethernet media access control method
developed in the early 1980s. To connect

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.

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 network is the Internet, a
worldwide network.

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