current LAN uses the Ethernet media access control

card or network interface card is required. To exchange

the hardware equipment. Windows XP uses TCP/IP as

the default protocol.

be slim. And because it does not blink, it reduces eye

strain.

Network

and scanners, connected by a communications link.

connected permanently through cables or temporarily

through telephone lines or wireless links. The biggest

computer waits before entering Standby Mode, or

before the monitor or hard drive turns off. The settings

are saved as a power scheme.
