LAN (Local Area Network)
A network which is accessible only to its
members, unlike the Internet which is
open to an unlimited number of people. A
LAN may be built for different purposes.
For example, you can build an office LAN
that is accessible only to members of the
same department or a home LAN that is
accessible only to family members.
Network Name (SSID)
A wireless LAN group identifier
according to the IEEE 802.11 standard.
SSID stands for "Service Set ID". The
Network Name can be set individually for
each Access Point and Peer to Peer
Network to connect to. When roaming
among multiple Access Points is used, all
Access Points must be configured for the
same Network Name (SSID) and WEP
encryption key.
TCP/IP (Transmission Control
Protocol/Internet Protocol)
TCP/IP is the network communications
protocol that is used to communicate over
the Internet. TCP is a connection-oriented
protocol for establishing reliable,
sequenced data transfer. TCP ensures that
data reaches its destination.
IP assembles and addresses data packets
for transmission to their network
destinations.
WAN (Wide Area Network)
A network that interconnects remote
LANs through the Internet or telephone
lines.
